DISPENSING PUMP Russian patent published in 2007 - IPC B05B11/00 B65D83/00 

FIELD: petrochemical industry; oil and gas producing industries; production of the dispensing pump.

SUBSTANCE: the invention is pertaining to the dispensing pump for the dosed without formation of the drips, issue of the liquid and up to paste-like products from the containers, for example, the bottles, the cans or the tubas. The pump consists of the lower part supplied with the suction inlet and the upper part with the movable cap for the product suction through the suction inlet of the lower part of the pump into the suction chamber and for the product issue through the distributing channel with the outlet from the suction chamber. With the purposes of construction simplification, the invention offers to form the lower end disposed under the cap of the suction chamber by means of the "floating" resilient valve diaphragm, which at the axial displacement of the cap due to bending of its central part alternately opens and closes the bottom outlet of the distributing channel disposed in the middle and simultaneously closes and opens the suction inlet of the lower part of the pump due to deformation of its external edge area.

EFFECT: the invention ensures simplification of the dispensing pump design and the increased efficiency of its operation.
