A valve mechanism in which a valve member is moveable into contact with a valve seat as a result of actuation of the valve. The valve seat and the valve closure member are designed such that they have essentially only line contact when the valve is closed, with the nominal width of the valve corresponding approximately to the sealing width of the valve. This construction allows a relatively large nominal width to be used for the flow cross section of the valve without the need for a much larger actuating force for the valve. To prevent damage to the valve seat and to the valve closure member, an elastic damping element may be disposed behind the valve closure member so that the valve closure member can deform compliantly up impact against the valve seat.

Valve mechanism

The invention relates to an electropneumatic coupling arrangement for providing a pressure-tight connection between a pressure supply line and a pressure chamber of a hydropneumatic component. The coupler includes a plastic plug-in body member having a pressure conduit and a plurality of electrical contacts for interconnecting an electrical sensing element located in the housing of the hydropneumatic component to apparatus located outside the hydropneumatic component.
