Abstract
A piston pump, in particular as a pressure generator in an electronically slip-controllable vehicle brake system, includes a pump cylinder, a drivable piston, a pump working chamber, a valve space, and a valve. The drivable piston is slidably accommodated in the pump cylinder. The pump working chamber is bounded by the piston and the pump cylinder. The valve controls a supply of pressure medium to the pump working chamber. The valve has a conical valve seat and a closing element having a domed shell section that interacts with the valve seat. The valve seat surrounds the valve space, into which the closing element plunges, at least up to an imaginary center point of the domed shell section, when the valve seat is closed or open.
