摘要： A differential pressure regulator is arranged in series on the inflow side of a variable throttle for adjustment of a flow rate. An inlet pressure of the variable throttle is led into a primary pilot chamber of the differential pressure regulator. A constant flow control valve is provided in an oil passage connecting an oil passage on the inflow side of the differential pressure regulator with a secondary pilot chamber in order to allow a fluid of a constant flow rate to flow. The inflow side of a sequence valve is connected to the side of the secondary pilot chamber of the differential pressure regulator. The outflow side of the sequence valve is connected to the outlet side of the variable throttle or a tank. The inlet passage of the variable throttle is led into the primary pilot chamber of the sequence valve. An outlet pressure of the variable throttle is led into the secondary pilot chamber of the sequence valve. Further a check valve or a throttle is connected in parallel to the sequence valve. A relief valve is provided in an oil passage starting from the outflow side of the constant flow control valve and reaching the tank in order to prevent an increase in peak pressure when a load stops and thereby to control the pressure.

摘要： A pressure control valve including a valve, a spring for pressing the valve, and a power input means for compressing the spring further comprises a backup force-generating mechanism for producing and directing a backup force counter to the direction in which the reaction force due to the compression of the spring is exerted on the input means, so as to impart the backup force to the input means.

摘要： A gyro apparatus including a gyro case for housing a gyro therein, the spin axis of which is selected to be substantially horizontal, a container for accommodating therein the gyro case and containing a liquid within it, a first supporting device for supporting the gyro case within the container, a second supporting device for supporting the container in a manner that the container may have the freedom of three axes, and a vertical follow-up device for making the container to follow-up the gryo case around a gravity line, in which there is further provided a device in connection with the container for substantially changing the gap formed between the container containing the liquid and the gyro case from the outside of the container so as to adjust the displacement between the center of gravity of the gryo case and the center of viscous force caused by the liquid acting on the gyro case.

摘要： The reversible-flow rotary-piston engine has a lobed rotor flexibly linked to a longitudinal shaft, rotating eccentrically in a lobed stator to generate variable-volume working chambers. A radial piston valve for each chamber controls flow hy selective connection to working-fluid supply/return manifolds. An annular disc (1) between valve plate and manifolds has a bore (1d) clearing the valve discharge ports. Perforations (1a) and blind recesses (1b), together equalling the number of chambers, grouped respectively to form integral subsets of this total, are evenly distributed around the disc. A peripheral groove (1c) links the recesses. Via the disc, fluid can be selectively directed to grouped chambers.
