    Abstract: A balance valve for maintaining two fluid pressure systems at a predetermined pressure relative to one another. The valve comprises a piston (2) slidably received within a bore (14), and subjected on opposite ends to the pressure in the two systems. Each of the systems is provided with a relief line (17, 20) whose communication with the associated system is controlled by movement of the piston such that any imbalance of forces acting on the piston causes the piston to be displaced to open the appropriate relief line to balance out the forces acting on the piston. Shock absorber means (25, 26, 28, 29) is provided to resist rapid movement of the piston, and respective springs (23, 24) may be provided for the purpose of centralizing the piston or for setting up a differential pressure in the two systems. The ports (21) of the respective relief lines are preferably triangular in shape such that a progressively greater area is uncovered in relation to the distance travelled by the piston.

    Abstract: In an hydraulic system a solenoid-operated valve means (1) is used to control delivery of pressure fluid to a part (20) of the system, the fluid being circulated by a pump (15) from a reservoir (14) through the valve means (1) and back.
    To provide a light, low-powered solenoid valve which is still able to deal with the pressure generated, the valve means (1) has a solenoid-operated valve (6) biassed open, and closed when the solenoid-operated valve (6) biassed open, and closed when the solenoid (12) is energised to generate pressure fluid, the valve (6) then being operated in response to the pressure and a pressure-responsive valve-opening means (7), such that when the pressure rises above a first threshold level the pressure acts to keep the valve (6) closed, until the pressure reaches a second threshold level at which the valve-opening means (7) is operative to cause the valve (6) to open provided the solenoid (12) is de-energised.
    The valve-opening means (7) comprises a valve (34) which opens at the second threshold level to allow pressure fluid into a cavity (37) defined by a piston (33) to cause the pressure to fall and the valve (6) to open.

    Abstract: This invention relates to a relief valve for controlling the pressure of a hydraulic fluid within a first duct (30) opening into a bore (14,16) provided in a housing (12), a communication between said first duct (30) and a second duct (34) connecting a primary hydraulic circuit under pressure to said bore (14,16) being provided in rest position of a valve member when the pressure within said first duct (30) is lower than a threshold determined by the preload of a resilient means urging said valve member in rest position, said communication being interrupted when said pressure in said first duct (30) sensibly reaches said threshold.
    According to the invention, an increase of said pressure in said first duct beyond said threshold results in providing a communication between said first duct (30) and a third duct (38) connected to a low pressure circuit.
