Claims (14)

1. Dispensing pump (1,1 ', 1' ', 1' '') for dosed dispensing without droplets from liquid to pasty product from containers, for example, bottles (26), cans or tubes, consisting of a suction port ( 4) the lower part (6.6 ', 6``) of the pump for fixing on the hole (5) of the tank, and the suction hole (4) through, for example, the tube (21) is brought into contact with the product, and from the upper part (8 8 ', 8' ') of the pump with a movable cover (10.10', 10 '') for suctioning the product through the suction hole (4) of the lower part (6) of the pump into the suction chamber (14.14 ', 14``) and for issuing the product from this suction chamber (14.14 ', 14``) through the dispensing channel (3) with an outlet (24), characterized in that the integral, made without through-hole elastic valve membrane (7) is "floating", t .e. flat and without fixing, it is superimposed on the suction hole (4) of the lower part (6.6 ', 6``) of the pump, and thus forms the lower end of the suction chamber (14.14', 14 ''); the lower part (3 ') of the dispensing channel with its lower hole (2) passes down the center directly to the valve membrane; the valve membrane (7) in the case of the bending of its central part caused by the movable cover (10.10 ', 10``), alternately opens and closes the centrally located lower opening (2) of the dispensing channel (3) and simultaneously, conversely, closes and opens the suction hole (4) of the lower part (6.6 ', 6``) of the pump due to deformation of its outer edge region (25). 2. The dispensing pump (1,1 ', 1' ') according to claim 1, characterized in that the elastic valve membrane (7) is made of a thermoplastic elastomer. 3. The dispensing pump (1,1 ', 1' ') according to claim 1, characterized in that the elastic valve (7) membrane is made of rubber. 4. The dispensing pump (1,1 ', 1' ') according to claim 1, characterized in that the elastic valve membrane (7) in the outer edge region (25) is formed by waves (22) made as corrugations. 5. The dispensing pump (1,1 ', 1' ', 1' '') according to claims 1, 2, 3 or 4, characterized in that the upper part (3 '') of the dispensing channel is partially bent out by its outlet ( 24) on the side of the top of the pump (8.8.8``). 6. The dispensing pump (1,1 ') according to claim 5, characterized in that the upper part (8) of the pump is connected to the lower part (6) of the pump through a container (26), and the lower part (6) of the pump is hermetically pressed into the hole (5) tanks, and the upper part (8) of the pump is connected to the tank (26) by means of a shock or screw lock, and the dispensing channel (3) is a dispensing pipe (3) formed motionlessly in the upper part (8) of the pump, above the upper the bent part (3 '') of the dispensing channel of which is hermetically fixed on the upper edge (9) of the upper part (8) of the pump, made constant prices of a resilient material such as a thermoplastic elastomer, axially deformable cap (10). 7. The dispensing pump (1,1 ') according to claim 6, characterized in that over the bent portion (3' ') of the dispensing channel on the upper inner side of the lid (10) there is a stop (13) that limits the axial movement of the lid (10) ) to the bent portion (3``) of the dispensing channel. 8. The dispensing pump (1) according to claim 7, characterized in that an axially movable protective cap (18) is mounted on the upper part (8) of the pump, the movement of which in the outward direction is limited by an annular protrusion (29,29 '). 9. The dispensing pump (1 ') according to claim 6, characterized in that the upper part (8) of the pump is connected to the hinged cover (12) by means of a hinge (11). 10. The dispensing pump (1``, 1 '' ') according to claim 5, characterized in that the upper part (8', 8``) of the pump is formed with the possibility of axial movement relative to the lower part (6.6 '') of the pump which covers the lower part of the upper part (8 ', 8``) of the pump, so that the upper part (3' ') of the dispensing channel and the cover (10', 10 ''), which are made as elements of the upper part (8 ', 8 '') of the pump can also move axially, while the lower part (3 ') of the dispensing channel as an element of the lower part (6', 6 '') of the pump with it is stationary when used, without the possibility of This movement is connected to the tank. 11. The dispensing pump (1``, 1 '' ') according to claim 10, characterized in that the suction chamber (14', 14``) is formed like a piston pump in the form of an annular space with an annular piston (32, 42), moreover, the annular space annularly and with rigid fixation surrounds the lower part (3 ') of the transfer valve, and the annular piston (32, 42) is connected to the upper part (3' ') of the transfer channel and, due to the lower part (3') of the transfer channel, the ability to move by sliding inside the annular space. 12. The dispensing pump (1``, 1 '' ') according to claim 10, characterized in that for returning to the initial position the axially moved upper part (8', 8``) of the pump at the end of the dispensing process inside the upper part (8 ', 8' ') of the pump, a return spring (33.43) is located, which rests on the lower part (6', 6 '') of the pump. 13. The dispensing pump (1``) according to claim 12, characterized in that the return spring (33) is located inside the dispensing channel (3). 14. The dispensing pump (1 '' ') according to claim 12, characterized in that the return spring (43) is located outside the dispensing channel (3) and the suction chamber (51).
