Definitions
- the invention also relates to a high-pressure pump for generating an injection pressure for fuel-operated internal combustion engines.
- Hydraulic pump units of the type mentioned in various embodiments are known from the prior art.
- Hydraulic pump units in which two pump elements are arranged at an angular distance of 180 degrees to one another.
- the pump elements of this known hydraulic pump unit are actuated from the inside by a camshaft that is perpendicular to the plane of the
- the invention proposes, starting from the hydraulic pump unit of the type mentioned above, that the number and the angular distance of the cams is matched to the number and the angular distance of the pump elements such that when a certain number of pump pistons are in the top dead center, is the same number of pump pistons at bottom dead center.
- Hydraulic pumps unit has an even number of pump elements, so that an equal number of pump elements can be actuated in opposite directions and at that point in time the same number of pump pistons in opposite delivery or
- the hydraulic pump unit according to the invention has O 00/50772
- the hydraulic pump unit according to the invention can be realized with a large number of different embodiments without thereby abandoning the idea of the present invention.
- the number and the angular spacing of the cams of the cam drive can be varied.
- the number and the angular spacing of the individual pump elements can also be varied.
- the number and the angular distance of the cams of the cam drive is matched to the number and the angular distance of the pump elements such that when the number of pump pistons is at top dead center, the same number of pump pistons in the bottom dead center. This is the only way to achieve an even delivery of all pump pistons with "partial filling".
- the cams of the cam drive drive the pump pistons from the inside with a
- the cam drive is designed as a cam, which runs perpendicular to the plane in which the pump elements lie, through the intersection and on the outer circumferential surface of which the cam is formed.
- the hydraulic pump unit has a particularly high running smoothness, in particular when the cam drive has high numbers of wires.
- the cam drive have three cams arranged at an angular distance of 120 degrees.
- the hydraulic pump unit then advantageously has two pump elements which have an angular distance of 60 angular degrees from one another. It is further proposed that the hydraulic pump unit has four pump elements which are at an angular distance of 60 angular degrees from one another. Finally, it is proposed that the hydraulic pump unit six
- the pump pistons deliver the hydraulic fluid to the radially outer end of the pump elements.
- the conveyed hydraulic fluid can then be led out of the hydraulic pump unit from the radially outer ends of the pump elements and fed to a high-pressure accumulator via feed lines located outside the hydraulic pump unit.
- the high pressure is shifted out of the housing of the hydraulic pump unit into the outer supply lines.
- the housing only has to be designed for low pressure and can be manufactured cheaper.
- the hydraulic pump unit as a high-pressure pump for generating an injection pressure for a fuel-driven internal combustion engine. Especially when used as
- a further object of the present invention is to design and further develop a high-pressure pump of the type mentioned at the outset in such a way that it enables the hydraulic fluid to be conveyed uniformly.
- the invention proposes, starting from the high-pressure pump of the type mentioned, that several of the hydraulic pump units according to one of claims 1 to 11 are arranged one behind the other in such a way that the pump elements of all hydraulic pump units are acted upon by the same cam drive with their actuating movement.
- the number and the angular distance of the pump elements of the hydraulic pump units and the angular displacement of the hydraulic pump units from one another are matched to the number and the angular distance of the cams such that when a certain number of pump pistons of the high pressure pump are located in the upper one Dead center is the same number of pump pistons in the bottom dead center.
- two hydraulic pump units according to claims 3 and 5 are arranged in such a way that the planes in which the pump units are located run parallel to one another and that the intersections of the
- the hydraulic pump units are advantageously arranged congruently one behind the other.
- the hydraulic pump units are arranged one behind the other rotated by an angular offset of 180 angular degrees.
- Hydraulic pump unit from FIG. 1 and FIG. 2;
- the hydraulic pump unit 1 is designed as a radial piston pump. It is used, for example, as a high-pressure pump 18 (cf. FIG. 3) for generating an injection pressure for fuel-operated internal combustion engines.
- the hydraulic pump unit 1 has two pump elements 2, which are arranged in one plane. Each pump element 2 has a pump cylinder 3 and a longitudinally displaceable therein
- the pump piston 4 is pressed radially inward in the direction of the intersection 6 by a spring element 7. In this position, a pump chamber 8 of the pump element 2 has its largest volume.
- the pump chamber 8 is filled with fuel from a metering unit 14.
- the pump chamber 8 leads out of the hydraulic pump 1 via a pressure valve 11 and a connecting piece 12.
- the pump piston 4 in the pump element 2 is pressed radially outward from the bottom dead center (UT) to the top dead center (OT) against the force of the spring element 7.
