A SWITCH-OVER VALVE, PREFERABLY FOR AN AIR DRIER |
摘要 |
<p>A switch-over valve for directing a compressed air flow to either one of two drying towers (7, 8) of an air drier, the other one being vented to the atmosphere.

A valve body (40) is axially movable in a cavity (41) in the wall between two positions sealing off either one of the outlets from the cavity and keeping the other one open. A control piston (39) with a greater length than the valve body is axially movable in a bore in the valve body and is biased towards a neutral position by spring means (46).</p> |
