Pressure control valve i.e. return valve, for use in pump assembly, has supporting element for supporting spring force of compressed spring at retention body, where element is formed as press element that is pressed into channel

摘要

The valve (4) has a closing body (5) cooperating with a valve seat (7) and axially fixed in a channel (3) i.e. borehole, against a spring force of a compressed spring (6). A supporting element is provided for supporting the spring force of the spring at a retention body (1). The element is formed as a press element (12) that is pressed into the channel. The press element is plastically and/or flexibly deformed in a pressed condition, where the press element is designed as a self sealing element. The press element is form-fittingly and/or friction-fittingly connected with the retention body.
