Document Type and Number:
Japanese Patent JP2006529017
Kind Code:
A
Abstract:
A valve, in particular, a proportional seat valve or gate valve, includes a valve housing (10) and at least three fluid connections (1, 2, 3) extending through the valve housing. A main piston (18) extends in the valve housing (10). A pilot piston (24) for executing a pilot control (26) may be controlled by a current-carrying magnetic device (28). During an open pilot control (26), fluid from one (2) of the connectors (1, 2), controlled by the main piston (18), reaches the connector (3), controlled by the pilot piston (24), by a cross-sectional narrowing (38) in the main piston (19). The pilot control (26) and, as a result of the corresponding pressure drop, the main piston (18) achieves a control position, controlling both fluid connections (1, 2) with regard to fluid amount.
