MULTI-STAGE SWITCHABLE PILOT-CONTROLLED VALVE ARRANGEMENT |
摘要 |
A pilot-controlled valve arrangement having at least one valve mechanism mounted in a valve housing for multi-stage switching of a compressed air flow between a feed pressure connection and a working line connection wherein a throttled compressed air flow can be switched in at least one switching stage by a throttle, wherein the pneumatic pilot control has a first control piston mounted in a first control chamber implemented in the valve housing and having a coaxial recess for forming a second control chamber in which a second control piston is mounted, so that an additive control pressure application to the control chambers generates a telescope-like deployment of a ram extending from the second control piston for generating a multi-stage switching stroke for the valve mechanism, in order to implement the throttled compressed air flow in at least one switching stage of the valve mechanism present between the closed and the open valve setting. |
