<p>The equipment regulates the stroke of a hydraulic ram, whose rod has a micrometer adjusting screw first acting on a valve shutting off the incoming fluid and then on a discharge valve. The shut-off valve (10) has its seat in the body of the discharge valve (24), and the incoming fluid flows through this body. The screw (4) acts on the shut-off valve stem (9), which in turn acts on the discharge valve. The two valves can be coaxial, the discharge valve being a piston working in a linear and having a central passage (23) connected by a radial one (29) to an annular chamber, which in turn communicates with a discharge passage (30).</p> |
