Abstract
The present invention related to a piston pump, in particular for controllable brake systems such as ABS or ESP, wherein a working chamber of the pump in front of a piston is delimited by a pressure valve, and a resetting spring with its one end is supported on a valve seat carrier of the pressure valve and with its other end resets said piston into its bottom dead center position. An object is to render the assembly of the mass-produced pumps as inexpensive and simple as possible. To achieve this object, the present invention discloses that the resetting spring be adapted to be attached directly or indirectly to the valve seat carrier in addition.
