ABSTRACT:
The invention relates to a pressure limiting valve with a hydraulic seal ring (12), characterized in that the sealing element (6), for securing the flow gap (10) between the consumer connection (3) and the pressurized fluid outlet (4), is embodied as a seal ring (12) with a limited flexibility. Said seal ring (12) is inserted without preload into a groove (13) provided therefore, whereby said groove (13) is embodied so as to allow the flow of pressurized fluid (11) behind the seal ring (12).
