ABSTRACT:
In the spool member of a multi-way-valve leakage of pressure fluid from the inlet port to the operating ports and a corresponding pressure increase in a consumer are prevented by annular grooves and radial bores through which pressure fluid leaking from the inlet is discharged to the reservoir. The radial bores are provided in the spool member so that the land relief between the pressure inlet port and the operating port is achieved via the spool member, and the housing of the multi-way-valve may remain unchanged.
