PRESSURE-MEDIUM CONTROL VALVE, PARTICULARLY FOR CONTROLLING A THROUGHFLOW DIRECTION IN A PRESSURE-MEDIUM CIRCUIT, AND PISTON PUMP, PARTICULARLY FOR PUMPING A PRESSURE MEDIUM IN AN ELECTRONICALLY SLIP-CONTROLLABLE VEHICLE BRAKE SYSTEM

摘要

The invention relates to a pressure-medium control valve (60), particularly for controlling a throughflow direction in a pressure medium circuit, and a piston pump (10), particularly for pumping a pressure medium in an electronically slip-controllable vehicle brake system. Known pressure-medium control valves (60) have a valve housing (62) produced by forming, a valve seat (64) and a valve-closing body (66) which is received in the valve housing (62) in an axially movable and radially guided manner and controls said valve seat (64) according to the prevailing pressure ratios upstream and downstream of the valve seat (64). According to the invention, the valve seat (64) is embodied as a single component with the valve housing (62). The pressure-medium control valve (60) can be produced by forming in a compact and cost-effective manner. It operates particularly quietly and can alternatively by used as an independent unit that can be tested before use.
