Abstract
A spool valve arrangement with a cylinder is fitted with a clearance fit in a cylinder bore in a housing of the spool valve arrangement. The housing has first pressure medium ports and the cylinder has second pressure medium ports. A socket is inserted through each first pressure medium port in the housing and each second pressure medium port in the cylinder. The socket has a small diameter part, which is fitted with a clearance fit in the second pressure medium port, and a large diameter part, which is engaged with a shoulder formed in the first pressure medium port. By screwing a conduit end in the first pressure medium port, the socket is held in the mounted position, thus providing a seal of the region of this port and also providing an anti-rotation effect on the cylinder relative to the housing.
