Abstract
The invention relates to a piston pump for conveying fluids. The piston pump includes a piston, and a pressure chamber located between an intake valve and a discharge valve. The intake valve is arranged between the pressure chamber and a low-pressure zone of the piston pump. The intake valve has a valve body, a closing element, a device for preloading the closing element, and a device for fastening the intake valve to the piston. The fastening device encompasses at least two fastening elements which protrude from the valve body toward the piston. The fastening elements are positioned at a distance from one another, and are fitted with inlets therebetween for supplying fluid. The invention further relates to a piston pump having an intake valve without a spring-biased element.
