PROPORTIONAL VALVE, IN PARTICULAR FOR A CAMSHAFT ADJUSTER

摘要

A proportional valve (1), including a piston guide sleeve (4) and a valve piston (3) that can be moved in the piston guide sleeve (4), and further including a check valve (13) arranged in a pressure medium inlet (10) to the proportional valve (1). According to the invention a proportional valve (1) is provided, in which the adaption of the check valve (13) to the proportional valve (1) is improved with respect to the prior art. This is achieved in that the check valve (13) is arranged in an annular gap (14) surrounding the piston guide sleeve (4) in a region of the pressure medium inlet (10).
