Abstract:
1. Screw-in solenoid-actuated multi-way seat valve made from steel for high pressure hydraulic applications, comprising a screw-in housing, a sleeve forming at least one valve seat, the sleeve being axially positioned in the screw-in housing, and an interior valve member having at least one seat surface with a larger outer diameter than the inner diameter of the valve seat, wherein the sleeve is axially positioned in the screw-in housing by a threaded connection and is sealed in the screw-in housing by a press fit zone formed by at least portions of two mutually contacting metallic circular cylindrical fitting surfaces in the screw-in housing and at the sleeve, which are axially pressed into each other, respectively, the press fit zone forming an anti-rotation protection for the threaded connection, wherein the axial position of the sleeve within the screw-in housing is adjustable by a relative rotational adjustment between the screw-in housing and the sleeve via the threaded connection and a rotation of the circular cylindrical fitting surfaces in relation to each other.
