    • PROBLEM TO BE SOLVED: To provide a three-way valve reduced in the number of parts items and assembling man-hour. SOLUTION: In this three-way valve, pressure chambers of a piston 3 for energizing a first main valve in a valve closing direction with a spring 8 and a piston 16 for energizing a second main valve, resisting energizing force of the spring 13, are connected to a middle-pressure port B through a pilot valve and a pressure passage 25. When the pilot valve is opened, high-pressure fluid from a high-pressure port A releases the pressure of the pressure chamber, which is led through an orifice 6, to the middle-pressure port B, and the piston 3 is pushed up by the high pressure to open the first main valve, and the spring 13 energizes a plug 10 to close the second main valve. When the pilot valve is closed, since the pressure inside the pressure chamber becomes high, the spring 8 pushes the piston 3 down to close the first main valve, and the piston 16 is pushed down by the high pressure to open the second main valve. With this structure, a two-way solenoid valve can be used as the pilot valve and the pressure passage 25 is formed inside a body 1 to reduce the number of parts items. COPYRIGHT: (C)2005,JPO&NCIPI

    • PURPOSE: To simplify the valve mechanism and reduce the production cost by a method wherein the one composite control valve and an valve for attachment are connected in parallel to the one pump and on the other hand the valve for attachment and the other composite control valve are connected with a pilot piping to the other pump.
      CONSTITUTION: When a remote control valve 69 is switched to the rightward position, the pressurized oil of a pump 68 switches the switching valve 55 of the secondary composite control valve 48, through the pilot piping 71, to the leftward position so as to operate an actuator by means of the pressurized oil of the pump 52 and the pressurized oil of the piping 71 also switches the selector valve 73 to the rightward position so as to close the logic valve 20 equipped on the primary composite control valve 11 and, on the other hand the pressurized oil of the pilot piping 72 switches the valve for attachment 32 to the leftward position so as to operate the actuator by means of the pressurized oil of the pump 15.

    • 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 (10) configured to provide intrinsic pressure regulation. The asymmetric pressure control valve (10), 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 (12) 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 (10), 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 (10) 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.
