WebbA cushion sleeve is mounted on the piston rod, so that as the rod extends, air ahead of the piston flows freely out the head-end port. When the end of the cushion sleeve reaches the lip of the check seal, it seals on the wall of the groove, trapping air for cushioning. As pressure is applied to the head-end port on retraction, WebbThis is a by-pass method of deceleration designed to reduce the forward speed of a cylinder piston when the cam valve position is reached. A part of the incoming oil supply is routed through an optional needle valve to the rod end port of the cylinder and to tank through the 4-way valve. Webb9 nov. 2024 · Cushion piston.
