摘要:
This invention relates to a valve with a valve housing which has several valve components. Sealing surfaces are provided on the circumference of the valve housing which correspond with a valve accommodating body carrying the valve housing. These surfaces are adapted to engage the valve accommodating body where (in dependence on the relative motion of the valve housing in respect of the valve accommodating body) the material volume existing on the circumference of the and plastically displace it into a circumferential recess of the valve housing.

The present invention relates to an electromagnetic valve which includes a valve housing with a valve seat member and a valve closure member controlled by a magnet armature, a valve coil arranged close to the magnet armature and delimited by a yoke ring, and a housing portion which closes the valve housing and on which the magnet armature is supported. The valve housing, the housing portion closing the valve housing, the yoke ring and the magnet armature are made of a magnetic-flux conductive material, and the magnetic circuit between the yoke ring and the valve housing is closed by way of a ferromagnetic annular piece fitted to the valve housing and/or by way of a ferromagnetic accommodating member which carries the valve housing.

The present invention relates to a valve arrangement which includes a hydraulically actuatable non-return valve (1) and another, preferably electrically actuatable valve closure member (7), which are both positioned in a valve-accommodating bore (8) of the valve housing (12) in which the valve arrangement is received, wherein both valve closure members (17) cooperate with a valve seat member (4) in the valve housing (12). The non-return valve (1) is configured as a plate-type non-return valve with a flow opening (2) which is aligned coaxially to a first opening (3) of the valve seat member (4). Relative to the first opening (3) at least one bypass opening (5) is provided in the valve seat member (4) which is either closed or opened by a sealing surface (6) located to the side of the flow opening (2) of the non-return valve (1). A compact non-return valve (1) which is especially simple to make is thereby achieved.
