    Abstract: The present invention describes, generally, a method and system for controlling the dynamics of an actuatable load functioning or operable within a servo or servo-type system, wherein the dynamics of the load are controlled by way of a unique asymmetric pressure control valve configured to provide intrinsic pressure regulation. The asymmetric pressure control valve, which may be referred to as a dynamic pressure regulator because of its capabilities, utilizes different sized free floating spools that are physically independent of one another and freely supported in interior cavities of respective corresponding different sized valving components that make up the valve body to regulate the pressures acting within the overall system between the control or pilot pressure and the load or load pressure. The dual spools of the pressure control valve, although physically independent of one another, function in cooperation with one another in an attempt to maintain a state of equilibrium in the system, namely to keep pressure acting on or within the actuator (the load pressure), or the feedback pressure corresponding to the load pressure, the same as the control or pilot pressure. Moreover, pressure regulation and control is intrinsic to the asymmetric pressure control valve because of the configuration and function of the dual spools and the feedback system acting on the spools, thus eliminating the need for electronically or mechanically user controlled systems.

    Abstract: A lift axle control module is disclosed that is simpler than prior art lift axle control systems, and does not require cycling the input pressure to the regulator. The module includes a housing fluidly connected to a first pressurized air supply and having one chamber with a load bladder port, a second chamber with a lift bladder port, and a common vent port. A pilot pressure is selectively provided for switching the module between the retracted and deployed modes. When the control module is set to the retracted mode, the lift bladders are pressurized to the system pressure, and the load bladders are vented. When the control module is set to the deployed mode, the lift bladders are vented and the load bladders are inflated and maintained at the regulated pressure.

    Abstract: The valve includes a body having five surfaces and a plurality of blind holes, grooves and channels interconnected with the blind holes to form communication net. Two rectangular diaphragms are embedded separately into the grooves so as to selectively open and close the blind holes. An internal sliding base with an external sliding base coupled to the external periphery thereof. and comprises a sliding section and an internal press pillar disposed separately on two corresponding ends of the bottom of the sliding section. The two internal press pillars are capable of selectively opening and closing the two diaphragms. The external sliding base includes an external press pillar disposed separately on both corresponding ends of the concave groove. A casing for covering the external periphery of the external sliding base is secured with the body. At least one elastic member is installed between the top surface of the casing and the external sliding base.

    Abstract: The object of the present invention is to provide a three-way valve reduced in the number of component parts and man-hours for assembling the component parts. A pressure chamber of a piston for urging a first main valve in a valve-closing direction by a spring, and a pressure chamber of a piston for urging a second main valve in a valve-opening direction against the urging force of a spring are connected to a medium-pressure port B via a pilot valve and a pressure passage. When the pilot valve is open, the pressure in the pressure chambers into which high-pressure fluid is introduced from a high-pressure port A via an orifice is permitted to escape to the medium-pressure port B, whereby the piston is pushed upward by the high pressure to open the first main valve, and a plug is urged by the spring to close the second main valve. When the pilot valve is closed, the pressure in the pressure chambers becomes high, so that the piston is pushed downward by the spring to close the first main valve, and the piston is pushed downward by the high pressure to open the second main valve. Since the pilot valve is formed by a two-way solenoid valve, and the pressure passage is formed within a body, it is possible to reduce the number of component parts.
