PCT No. PCT/EP95/02946 Sec. 371 Date Apr. 28, 1997 Sec. 102(e) Date Apr. 28, 1997 PCT Filed Jul. 26, 1995 PCT Pub. No. WO96/05090 PCT Pub. Date Feb. 22, 1996The invention pertains to a valve unit, comprising a valve housing (8) with a flow control valve, an electromagnetic actuating element (1) that is structurally arranged in series with the flow control valve in the valve housing (8), and a piston (3) that forms the flow control valve and produces an unobstructed pressure medium connection between a pressure medium source (4) and a pressure medium sink (5) in its normal position. In its normal position, the actuating element (1) is supported on one end face of the piston (3) against the force of a compression spring (2). In the operating position, the actuating element separates from the piston (3) and assumes an intermediate position in which it controls the volume flow of the pressure medium between the pressure medium source (4) and the pressure medium sink (5). This results in a simple and reliable valve construction. |
