<p><P>PROBLEM TO BE SOLVED: To provide a new fluid control system for a chair which requires the smallest number of hydraulic circuit control frameworks. <P>SOLUTION: The fluid control system is provided with: chair actuators 22, 24; a reservoir 44 to hold fluid; a pump 42; and a fluid flow circuit which supplies pressurized fluid to the chair actuators 22, 24, returns the fluid from the actuators 22, 24 to the reservoir 44, and connects the pump 42 so that it operates on the reservoir 44 and the actuators 22, 24. The fluid flow circuit has valves 48, 50 which operate selectively so that the return of the fluid from the actuators 22, 24 to the reservoir 44 is controlled, fluid pressure accumulators 74, 76 which are connected between the pump 42 and the chair actuators 22, 24, and between the chair actuators 22, 24 and the valves 48, 50, and flow control valves 54, 56 which are connected to a circuit between the chair actuators and the accumulators. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
