A valve of the pump has a seat fixed without possibility of motion, a disk with two rod guides, a sealing element and springs. The valve disk is made with mounting seat for the shutoff element and openings for liquid flow. The shutoff element is placed directly over the disk and moves over the upperguide, the long bosses on the disk and the shutoff element are intended for placing small spring. At such implementation of the valve the suction effect decreases, and as result the rate of the disk fit is decreased, this makes it possible to decrease the force of impacts and to prevent early emergence of defects and destruction of surfaces in contact of the disk and the seat.
