    摘要: Switchable pressure-limiting valve having an electromagnet (1) and a device (2) for opening and closing a passage for a fluid flow. The opening of the valve is determined by the balance of forces on the tappet (3), on which the pressure force of the fluid at the P connection (4), the pressure force of the fluid at the T connection (13) and the force of two springs (5) (6) act. The force of the spring (6) is modified by the position of the armature of the electromagnet. If the pressure force at the P connection (4) outweighs the sum of the other forces, the valve opens. The above-mentioned device for opening and closing consists of a diaphragm (7) and a sealing seat (12), and said diaphragm is clamped sealingly between the magnet pole (10) and the housing (21).

    摘要: A multi-mode pressure relief valve includes a body having fluid inlet and outlet ports and a compressed gas inlet port. The fluid ports and gas port isolated from one another. A reciprocating piston is in communication with the gas port. A valve stem is movable between an open condition and a closed position to permit and stop flow communication between the fluid ports. A spring is disposed between the valve stem and the piston and urges the piston and valve stem away from one another. The valve is operable in at least three modes, an operating mode in which the valve is open, the stem is spaced from the piston, and the piston applies pressure on the stem, and in which the pressure is balanced by fluid pressure the inlet, a zero-state mode in which the valve is open, the stem is spaced from the piston, the spring is in a relaxed state, and the piston applies no pressure on the valve stem, and a relief mode in which the valve is open, the stem contacts or is in close proximity to the piston and the spring is in a compressed state due to the fluid pressure.

    摘要: A relief valve (1) includes a valve body (2) having a first port (11) through which fluid flows in and a second port (12) through which the fluid is discharged, a sleeve (4) arranged so as to be slidable within the valve body (2) and formed with an inlet (7) being communicatable with the first port (11) and an outlet (8) being communicatable with the second port (12), a valve (5) being slidable within the sleeve (4) by receiving a fluid pressure of the first port (11) flowing through the inlet (7) in order to establish a closing state at which the outlet (8) is closed by the valve (5) and an opening state at which the outlet (8) is opened, a biasing member (6) applying a biasing force to the valve (5) and a valve position adjusting mechanism (13) actuated for operating the fluid pressure of the first port (11) so as to act on the sleeve (4) in a direction of the biasing force of the biasing member (6) and changing the position of the sleeve (4) relative to the valve body (2) by turning on or off the operation of the fluid pressure of the first port (11) so as to act on the sleeve (4).

    摘要: A pressure actuated valve assembly includes a valve body. The downstream end portion of a main spring (106) is engaged with a downstream end portion of the valve body and the main spring is axially aligned with the valve body. A main spring guide (110) is engaged with an upstream end portion of the main spring (106) proximate an upstream end portion of the valve body. The main spring guide (110) is mounted for movement toward the downstream end portion of the valve body by compression of the main spring. A hold-down sleeve (116) is engaged with the downstream end portion of the valve body and includes a stop structure proximate the main spring guide. The stop structure is configured to engage the main spring guide (110) to maintain a predetermined minimum clearance between the main spring guide and the upstream end portion of the valve body with the valve body in the closed condition.

    摘要: An exhaust pressure control apparatus is disclosed. The exhaust pressure control apparatus including a main body in which an inlet port and an outlet port are formed, the main body also including a pilot chamber. The system also includes a spool comprising an upper slide and a lower slide, the upper slide forming a movable portion of the pilot chamber, and the spool is held by the upper slide and the lower slide so that it can slide in an axial direction over a sliding surface connecting the intake port and the discharge port. A control system regulates a pressure in the intake port by controlling a pressure regulating gas supplied to the pilot chamber, and a control status portion provides an indication of the stability of the control system based upon the pressure in the pilot chamber.
