A pressure adjustment apparatus comprising a compartment (15) and a valve arrangement (10) for controlling the pressure of the compartment (15). The valve arrangement (10) comprises an inlet (12), for connecting the valve arrangement to a pressurised fluid source (13), and an inlet valve (14), for controlling the flow of fluid from the fluid source (13) into the valve arrangement (10); an outlet (16), for releasing fluid from the valve arrangement 34 (10), and an outlet valve (18), for controlling the flow of fluid out of the valve arrangement (10); a compartment port (20) by which the compartment (15) is connected to the valve arrangement (10); and a compartment valve (22) for controlling the flow of fluid into and/or out of the compartment (15). The compartment valve (22) is configured for simultaneous actuation to an open position with the inlet valve (14) and/or the outlet valve (18), such that when either the inlet valve (14) or the outlet valve (18) is in an open position, the compartment valve (22) is in an open position, such that the flow of fluid into and/or out of the compartment (15) is allowed.

The present invention provides a rocker valve comprising a valve body including first and second fluid ports and a rocker valve mechanism in the valve body. The mechanism comprises a single pivot arm rotatable relative to the valve body, and first and second plungers pivotally fixed to the single pivot arm. The second plunger acts in opposition to the first plunger when the single pivot arm is pivoted relative to the valve body. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports. The flexible seal member has a first sealing region attached to the first plunger and a second sealing region attached to the second plunger and is movable by the first and second plungers between a first position in which the first fluid ports is closed by the first sealing region, and a second position in which the second fluid port is closed by the second sealing region. When the single pivot arm is pivoted relative to the valve body, a rotation of at least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member.

A valve actuator (6) selectively opens and closes a plurality of valves (8). The actuator includes a drive motor (5) that selectively rotates a first rotor (4) about an axis (0) in first and second rotational directions. A second rotor (2) is rotatable about the axis only in the first rotational direction. Actuating fingers (3) are movably mounted in operative connection with the first rotor through drive pins (4a) and are guided to move radially by guides (2a) positioned on the second rotor. A coupling including drive rods (4b) which extend from the first rotor and are movable within arcuate slots (2b) on the second rotor, enables relative rotational movement of the rotors and the outer ends of the actuating fingers to be selectively radially extended and retracted. The outer ends of the actuating fingers are engaged with one or more valves to control the flow of working fluid.

A leveling valve includes: a seat portion configured to define a flow passage, the flow passage communicating with the air cushion and a compressed air source or communicating with the air cushion and a drain; a valve configured to move in an axial direction in accordance with a relative displacement of the vehicle body with respect to the truck; a spring configured to bias the valve toward a closing side, the valve being in contact with the seat portion in the closing side; a valve guide configured to support one end of the spring, the valve guide being slidably inserted with respect to a housing inner wall surface; and a communication port opened to the housing inner wall surface. A moving region in which the valve guide moves is set to a position offset from the communication port in the axial direction.

A two-route switching water output system includes a water input converter and a water output device. The water input converter includes a water input valve body and a valve cock.
