System pressure actuated by=pass valve for servomotor

摘要

The control, by-pass valve contains a valve plug (24) axially slidable in a valve housing (22). There is at least one valve spring, acting on the valve plug, in a spring chamber radially widened w.r.t. the valve plug. A two-arm spring bracket element (30) forms the valve spring and has a middle section, acting on the valve plug. Its arms (36) extend on either side transversely to the valve plug axis. The ends, radially spaced from the valve plug, are fixed to the valve housing.
