Abstract: An aspect of the present disclosure relates to a steering system having first and second steering circuits in fluid communication with a fluid actuator wherein the steering circuits are disposed in parallel to each other. The second steering circuit includes a proportional valve having a load-sense feature in selective fluid communication with a load-sense connection and the first steering circuit. The load-sense feature is open to the first steering circuit when the proportional valve is in a neutral position and closed to the first steering circuit when the proportional valve is moved to a first or second steering position. When the proportional valve is actuated from the neutral position to the first or second steering position the movement of the proportional valve closes the load sense feature from the first steering circuit and operates to deactivate the first steering circuit.

Abstract: A front panel opening/closing system includes a hydraulic cylinder, a tilt cylinder, a tilt pump, and a valve. The hydraulic cylinder is connected to a front panel of a cap to perform an operation of opening/closing the front panel. The tilt cylinder is connected to the cap to perform an operation of tilting the cap.

Abstract: A hydraulic soft-start system includes a first flow restricting orifice and a flow control valve both being in fluid communication with a pressure source and an inlet of a motor. Also provided is a second flow restricting orifice disposed between a pilot for actuating the flow control valve and the inlet of the motor. A first flow is passed from the pressure source via the first orifice to an inlet of the motor, placing the motor in a partially-actuated state. The flow control valve is actuated after a threshold pressure of the pilot is reached allowing a second flow to pass from the pressure source to the motor inlet. The second flow is higher than the first flow, thereby placing the motor in a fully-actuated state.

Abstract: A hydraulic pressure control apparatus includes a primary regulator valve that regulates a pressure discharged from an oil pump to form a line pressure that is used as an original pressure for a hydraulic pressure that is supplied to each element, and a secondary regulator valve that regulates a hydraulic pressure downstream of the primary regulator valve to form a secondary pressure. Two pilot pressures (first modulator hydraulic pressure, control hydraulic pressure from a duty solenoid) are supplied to the secondary regulator valve. The secondary regulator valve is configured in such a manner that when one of the pilot pressures changes, a change in the one of the pilot pressures is absorbed by the other pilot pressure.

Abstract: A hydraulic actuator is configured to provide redundant boost control to an aircraft within approximately the same space required by a single hydraulic cylinder. The hydraulic actuator includes a housing and a piston assembly disposed within the housing. The piston assembly includes a ram, a first piston secured to the ram, and second and third pistons disposed on the ram such that the second and third pistons are translatable relative to the longitudinal axis of the ram. The pistons form two hydraulically separate actuator cylinders within the space required by a single cylinder which results in a reduction in the weight and size of the hydraulic actuator.

Abstract: A hydraulic motor is driven by a fixed displacement, three stage gear-type pump. The three equal displacement sections provide 3 equally-stepped flows so that the hydraulic motor can have three speeds. Valving and controls are provided for remote on-the-fly shifting of the speeds, automatic pump unloading in neutral, and adjustable maximum pressure. A closed loop system permits use of a relatively small reservoir. The contamination tolerance of the system is greater than that of variable displacement piston-type pumps typically used. Direct recirculation of hydraulic fluid is provided for unused speeds to permit hydraulic fluid to recirculate in the pump without doing work. A unique control circuit is provided to control the first speed valve in conjunction with a logic cartridge which controls hydraulic motor direction to permit fluid flow to the hydraulic motor to be stopped when coming to neutral without slamming the hydraulic motor and rotating drill pipe to a stop. The first speed valve also acts as a relief valve to provide a mechanism for adjusting maximum system pressure.

Abstract: A pressure selector valve (13) is provided between a hydraulic motor (1) and a directional control valve (5) to connect one of the main conduits (4A), (4B) on a high pressure side to a high pressure conduit (14) while connecting the other of the main conduits on a low pressure side to a low pressure conduit (15). As an inertial body approaches a stop position, a spool valve (16) is switched to an open position (e), bringing a branch passage (14A) of the high pressure conduit (14) into communication with the low pressure conduit. When the pressure difference between the main conduits becomes small, the pressure selector valve is automatically returned to a neutral position to cut off communication between the main conduits, suppressing a reversing movement of the hydraulic motor so that an inertial body can be brought to a stop smoothly.
