  • Publication number: 20250207673
    Abstract: A directional valve including a valve housing, in which a slide receiving space is formed extending in a longitudinal direction and limited radially outwards by a peripheral receiving space boundary surface, in which a plurality of valve channels open, which pass through the valve housing and are spaced in the longitudinal direction at points in the peripheral receiving space boundary surface, and in which a valve slide, having at least one slide body, is arranged, which is displaceable in the longitudinal direction between a plurality of switch positions by executing a switching movement, and with at least one check valve member, which is movable relative to the slide body depending on the applied pressure difference, a receiving chamber is formed in the slide body. The check valve member is arranged axially movable and which is connected to the feed channel via a connecting channel formed in the slide body.

  • Publication number: 20240401708
    Abstract: A valve for controlling fluid flows, including a valve housing in which a control bore extends along a bore axis, in which a first valve member is moveably accommodated along the bore axis between a first open position and a first closed position for a first fluid channel and in which a second valve member is moveably accommodated along the bore axis between a second open position and a second closed position for a second fluid channel and further including a first drive assigned to the first valve member and a second drive assigned to the second valve member, in which a helical compression spring extends along the bore axis from the first valve member to the second valve member and has a central spring section with a central coil pitch which is at least virtually identical to a wire diameter of the compression spring.

  • Patent number: 12085177
    Abstract: A valve arrangement has two main valves which are each preloaded by a spring device into a first switching position, and which can each be switched into a second switching position by means of an assigned pilot valve. The pilot medium required for switching is provided with a pilot pressure at a pilot connection of each pilot valve. The main valves are each equipped with a working valve section each of which are fluidically connected to one another. In addition, each main valve contains a monitoring valve section. The monitoring valve sections are designed to provide the venting of at least one pilot connection when the two main valves are in different switching positions. This allows a fluid-actuated actuator to be controlled in accordance with high safety standards.
