Title: Multistage control device of pressure in hydraulic circuit
Inventor: SUDO MAKOTO
IPC: F15B11/02
Filed: 1989-10-12
Abstract: PURPOSE:To eliminate discrepancy between a set value and an actual value of operating hydraulic pressure by determining the operating hydraulic pressure of a main relief valve through operating some of remote controlled valves by means of electro- magnetic directional control valves provided in by-pass lines of the remote controlled valves connected to a vent of the main relief valve in series. CONSTITUTION:When an actuator 1 is stopped, electro-magnetic directional control valve 11a to 11h are not magnetized, and by-pass lines 12a to 12h are opened. In this case, working fluid flows through a vent of a relief valve 4 and the by-pass lines 12a to 12h Consequently, the main relief valve 4 is unloaded. When the actuator 1 is driven and some or all of the by-pass lines 12a to 12h are closed, pressurized working fluid pass through remote controlled valves 10a to 10h. Then, differential pressure, which is equal to the operating pressure, is produced before and behind the remote controlled valves 10a to 10h. Consequently, the sum of the said operating pressure is applied to the vent of the main valve 4. By this constitution, it is possible to set the operating pressure of the main relief valve 4, i.e., the operating pressure of the hydraulic circuit, multistagewise.

Title: Automatic transmission
Inventor: TANIGUCHI TAKUJI
IPC: F16H3/44
Filed: 1987-10-21
Abstract: PURPOSE:To prevent shift shocks upon a gear shift from a second speed stage to a third speed stage by coupling a hydraulic actuator for operating a clutch, to an input shaft. CONSTITUTION:Upon a gear shift a second speed stage into a third speed stage, a direct clutch C2 slips in an initial engagement condition even high centrifugal hydraulic pressure is effected by rotating the hydraulic actuator 40 at a high rotational speed in association with the rotation of an input shaft 26 since only a small amount of hydraulic oil is fed to a piston 51 in the actuator 40 at an initial stage of the gear shift. Further, a large amount of hydraulic oil is gradually fed so as to move the piston 51 leftward, gradually, overcoming a spring. When the clutch starts to shift from slipping condition into an engaging condition, the rotation of the input shaft 26 starts to steeply decrease, and simultaneously, centrifugal hydraulic pressure is abruptly reduced. Accordingly, the direct clutch C2 engages smoothly while gradually reducing affection by the centrifugal hydraulic pressure without shift shocks being generated.
