摘要
A minimum pressure valve for a screw compressor for a vehicle, in particular a utility vehicle, is provided with a housing; a valve insert opening which is formed in the housing; a valve insert which is inserted into the valve insert opening and has a valve piston bore; a valve piston, a valve piston section of which is guided in the valve insert in a movable manner in the valve piston bore; at least one fluid inlet channel; and at least one fluid outlet channel. The fluid inlet channel has at least one valve seat on the inlet channel end which faces the valve piston, wherein the valve piston can be set against the valve seat in order to close the minimum pressure valve such that the fluid inlet channel and the fluid outlet channel are separated in a closed position of the valve piston. The valve seat has a valve seat diameter dA, and the valve piston section has a valve piston section diameter dB. The ratio of the valve piston section diameter dB to the valve seat diameter dA ranges between ca. 0.6 and ca. 0.95.
