Valve device, such as main flow control valve for use in hydraulic hybrid powertrain, has sealing element that is designed substantially in pressure balanced way and is directly actuated by magnetic device

摘要

The valve device (1) has a sealing element (20), by which a magnetic device (25) is movable into an open position from a closed position by using an anchor (24), where a check valve (10) is integrated in the valve device. The check valve caused the opening of the sealing element, when a pressure at first pressure connection (2) is greater than second pressure connection (3). The sealing element is designed substantially in a pressure balanced way and is directly actuated by the magnetic device.
