摘要： A valve includes a valve axis extending in an axial direction, a valve housing, a ring that surrounds the valve axis, a seal, a spring for exerting a spring force, and a piston arranged in the valve housing. The valve housing includes a first valve housing opening through which a flow medium can pass. The ring is secured to the first valve housing opening. The seal is held on the valve housing by the ring. The piston is coaxial to the valve housing on the valve axis and axially faces the first valve housing opening. The piston is axially movable in the valve housing against the spring force, and the first valve housing opening can be closed by the piston.

摘要： A clutch (1) with an inner ring (2) arranged about an axis of rotation (d) and an outer ring (3) arranged coaxially in reference thereto, as well as an elastic clamping ring (4) arranged between them and radially limited thereby, with the inner ring (2) and the clamping ring (4) resting on each other via a ramp device (9), arranged bi-directionally effective in the circumferential direction, and clamping segments (13) pointing radially outwardly and arranged distributed in the circumferential direction, form in case of a radial displacement of the clamping ring (4) forming with the outer ring (3) a clamping connection in at least one circumferential direction. In a further aspect, a radial displacement of the clamping ring (4) is provided via a ramp device (12) effective in the axial direction, switched by an axial displacement of the inner ring (2) in reference to the clamping ring (4).

摘要： A valve having at least one valve housing and at least one piston. The valve housing (7) has a hollow-cylindrical first portion (11) with a first diameter (D1) and a second portion (12), connected to the first portion (11), with a second diameter (D2); a first opening (15) is formed on the end face of the valve housing (7) and at least a second opening (16) is formed in the second portion (12); and the first diameter (D1) of the first portion (11) is greater than the second diameter (D2) of the second portion.

摘要： A valve device includes a valve socket with a valve seat having internal radius, a valve disposed in the valve socket, and a first flow channel. The valve includes a valve housing, an inlet opening, a flow opening, and a stop. The valve housing includes a first housing portion sitting in the valve seat, and a second housing portion adjoining the first housing portion. The inlet opening is formed opposite the first housing portion and the flow opening is formed on the second housing portion. The stop sits on the valve housing at the inlet opening and radially protrudes beyond the valve housing. The stop includes a radial stop dimension greater than the valve seat internal radius, the radial stop dimension being a smallest radial distance between the valve axis and an area of the stop farthest from the valve axis. The first flow channel leads to the inlet opening.

摘要： A valve includes a valve housing and a piston. The housing has an end face with a first opening, a second opening with a closing edge, and a valve seat. The piston has a first surface pointing towards the end face, a first lateral surface, a control edge, and a second lateral surface. In a first switching mode, the first surface covers the first opening, the piston seals with the valve seat, the second opening is closed by the second lateral surface, and the control edge is between the closing edge and the valve seat. In a second switching mode, the second opening is closed by the second lateral surface and the control edge is between the closing edge and the valve seat. In the third switching mode, a section of the second opening is released to form a flow chamber permeably connecting the first opening and the second opening.

摘要： A device includes a component and a valve housing The valve housing is arranged in a hole in the component and is at least partially enclosed by the wall of the component The component includes a first channel having a channel port extending into the hole. The valve housing includes two first ports arranged adjacent to each other about a center axis of the valve housing and opened radially, in the direction of the center axis, into an interior of the valve housing. The valve housing included a bridge arranged circumferentially between the two first ports. The two first ports are partially defined by the bridge. At least one section of at least one first port is arranged radially opposite the channel port such that a radially first passage through which flow medium can pass is formed between the first channel and the interior of the housing. An outer width of the bridge determined at an outer lateral surface of the valve housing is less than an inner width of the channel port determined at the hole.

摘要： A valve includes a valve housing, a piston, a support element, and a spring. The piston and the valve housing are arranged coaxially to each other on an imaginary valve axis. The piston is received in the valve housing in an axially movable manner against the spring force of the spring. The spring is supported on the support element and on the piston. The valve housing is provided with a first opening through which a fluid can flow and which can be closed by a piston base of the piston. The valve housing is provided with a second opening which can be at least partly closed by a piston casing of the piston and through which the fluid can flow. The piston casing extends outwards from the piston base in the axial direction of the support element and surrounds the valve axis.
