Description

Hydraulic / pneumatic bottle

Object of the invention

The present Utility Model application It aims at registering a hydraulic / pneumatic bottle that incorporates notable innovations and advantages over bottles existing hydraulic / pneumatic

More specifically, the invention relates to a hydraulic / pneumatic bottle equipped with two pistons that can Work together or separately.

Background of the invention

Bottles are widely known hydraulic or pneumatic linked to shearing machines or presses, which allow a quick and effective action on the material to handle. However in known devices, when a large cutting or pressing power is required, it is need to install more hydraulic bottles or replace the bottle existing hydraulics by another one of a much larger diameter to consequently increase the available force. In any of the two situations, solutions are adopted that increase the system complexity and they take up a lot of space.

In addition, the applicant is not aware of the existence of a hydraulic / pneumatic bottle that presents all the technical and structural characteristics described in this memory

Description of the invention

The present invention has been developed with the in order to provide a hydraulic / pneumatic bottle that solves the aforementioned drawbacks, also providing other additional advantages that will be apparent from the Description attached below.

It is therefore an object of the present invention provide a hydraulic / pneumatic bottle formed by two substantially cylindrical and adjacent parts, presenting a first part a diameter smaller than the diameter of the second part, said hydraulic / pneumatic bottle being characterized by the fact that said first part is comprised of a first shirt and a first piston and said second part is comprised of a second jacket and a second piston, the first and second piston by a common and hollow rod, fixed by one end to the base of the second part and at the other end to first piston, said first sleeve being integral with the second piston that is movable along said rod.

Said first shirt describes a movement axially ascending-descending in relation to said first piston and said second piston an axial movement ascending-descending in the second shirt, being configured said first piston so that its upper face defines a top chamber in conjunction with said first shirt, being configured said second piston so that its lower face defines a lower chamber in conjunction with said second shirt, and a communication hole having been provided in said first shirt so that the first part and the second part are communicated, said second shirt presenting an element of tightness around said first shirt, being preferred said sealing element a sealing collar.

In addition, an intermediate chamber is defined in the space between the lower face of the first piston and the upper face of the second piston.

The hollow stem has an open end which ends in said upper chamber, so that when a fluid pressurized is arranged in the intermediate chamber, the first piston compresses a fluid lodged in the upper chamber introduced into the open end of the rod, and the second piston compresses a fluid located in the lower chamber that is evacuated through a opening made in the second shirt.

Thanks to these characteristics, you get a hydraulic / pneumatic bottle that increases the force available in any machine or tool such as shears or presses, without increase the dimensions of the bottle, especially in terms of diameter. By having a second piston inside the bottle hydraulic / pneumatic the surface on which the fluid is increased exerts pressure and consequently optimizes the use of space.

Preferably said rod presents by at least one hole at the bottom of the lower chamber so that said upper chamber and said lower chamber are communicated. From This way the two pistons work together.

The fluid located in the upper chamber and in the Bottom chamber of the hydraulic / pneumatic bottle object of the invention may advantageously be air or oil.

On the other hand the first piston and the second piston each comprise a central segment and two joints of tightness at opposite ends. The second piston presents also some O-rings in the area of contact with the stem.

In an alternative embodiment of the invention, the stem is attached to the base of the hydraulic / pneumatic bottle but it has no hole. In this way the upper chamber and the lower chamber are not communicated and the pistons work separately.

Other features and advantages of the bottle Hydraulic / pneumatic object of the present invention will result evident from the description of a preferred embodiment, but not exclusive, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

Description of a preferred embodiment

As shown in the attached figures, illustrate two preferred embodiments of a bottle hydraulic / pneumatic, indicated in general with reference 1, in accordance with the present invention.

In figure 1 you can see a first realization of the hydraulic / pneumatic bottle 1 formed by two substantially cylindrical parts, with a first part 2 of diameter smaller than the diameter of the second part 3.

This first part 2 comprises a first jacket 4 and a first piston 6 and in turn said second part 3 it comprises a second jacket 5 and a second piston 7, being related the first piston 6 and the second piston 7 by a rod 8 common and hollow, fixed at one end preferably to the base of the second part 3 and at the other end to the first piston 6, being said first sleeve 4 integral with the second piston 7 that can be move along said rod 8. Preferably the first jacket 4 is attached to the second piston 7 by screws and in parallel, the second piston 7 has O-rings in the contact zone with the stem, rings that have not been represented in the attached figures.

Said first shirt 4 describes a movement axially ascending-descending in relation to said first piston 6 and said second piston 7 a movement axially ascending-descending in the second shirt 5.

Said first piston 6 is configured so that its upper face defines an upper chamber 9 in conjunction with said first jacket 4, and in parallel said second piston 7 it is configured so that its lower face defines a camera bottom 10 in conjunction with said second shirt 5. advantageously a communication hole 11 is provided in said first shirt 4 so that the first part 2 and the second part 3 are communicated. In addition to ensure the tightness between the two shirts, the second shirt 5 has a sealing collar 19 around said first shirt 4.

In the space between the lower face of the first piston 6 and the upper face of the second piston 7, is define an intermediate chamber 12.

The open end of the hollow rod 8 ends in said upper chamber 9, so that when a pressurized fluid in intermediate chamber 12 through a inlet 13, the first piston 6 compresses a fluid housed in the upper chamber 9 that is introduced through said open end of the rod 8, and the second piston 7 compresses a fluid located in the lower chamber 10 which is evacuated through an opening 17 practiced in the second shirt 5.

In this first embodiment said rod 8 advantageously has at least one hole 18 at the height of the lower chamber 10 so that said upper chamber 9 and said lower chamber 10 are communicated. In this way it is possible to do work both pistons together, raising power available without increasing the diameter of the set.

The bottle is planned hydraulic / pneumatic 1 object of the present invention can compress air or oil interchangeably, located in the chamber upper 9 and in the lower chamber 10. In addition the first piston 6 and the second piston 7 each comprises a central segment 15 and two gaskets 14, 16 at opposite ends.

In a second embodiment of the invention, as illustrated in figure 2, the stem 8 is firmly attached to the hydraulic / pneumatic bottle base 1 but does not have any hole as in the first embodiment. In this way the camera upper 9 and lower chamber 10 are not communicated and the Pistons work separately.

In the two attached figures they have been indicated with arrows the path that describes the fluids in the bottle hydraulic / pneumatic 1, and the sleeves have been sectioned for a Better understanding of the invention.

The details, the shapes, the dimensions and other accessory elements, as well as the materials used in the manufacture of the hydraulic / pneumatic bottle of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention or of the scope defined by the claims to be include below.
