摘要： A protection device for controlling the motion of a pneumatic actuator (3), comprising at least one elongated cylinder (6) provided with a piston (4), dividing the cylinder (6) into a first chamber (5a) and a second chamber (5b), an actuating pressure supply line (14) connectable to at least one of said first and second chambers (5a, 5b), a control means (22) for controlling the motion of the piston (4) relatively to the cylinder (6), and a sensor means (23, 30) adapted to sense a piston feature related to the piston motion and being co-operating with the control means (22). According to the invention, said control means (22) limits the motion of said piston (4) as soon as signalling from said sensor means (22, 30) indicates that an excessive value of said piston motion has been established.

摘要： An aircraft flap drive system utilized a variable displacement motor (15) having a fluid pressure actuated means (23) to vary the displacement of the motor. The system includes a displacement control valve (41), and an electrohydraulic control means (55,67,85) operable in response to an electrical input signal (91) to communicate pressurized fluid from a source (11) to the motor. The displacement control valve (41) includes a load sensing arrangement (13,53,49) responsive to an increasing load on the motor to bias the displacement control valve toward a position whereby the motor moves toward its maximum displacement (minimum flow). One result is that the conventional fixed displacement motor, of a particular size and weight, may be replaced by a variable motor which is smaller and lighter.

摘要： A process is disclosed for exactly positioning the tilting outfit (1), in particular the shovel, mounted on the descending lift frame (1) of a movable construction machine, in particular a wheel-mounted loader. Logical circuits (13) co-operate with automatic positioning means (14) so that when the latter are actuated the logical circuits (13) switch a solenoid valve (20) and move the tilting piston (24) of a control valve (25) into a position in which oil fed by a pump (16), in particular a regulated pump, can flow to the tilt ram (6). As the piston rod (7) of the tilt ram (6) is extended, the path covered by the piston rod (7) is measured at several predetermined spots. The first measurement value triggers a signal that causes the logical circuits (13) to activate another solenoid valve (21) or to deactivate at the same time the first solenoid valve (20), placing the tilting piston (24) in a position in which oil flow to the tilt ram (6) is reduced to a predetermined extent. The extension of the piston rod (7) is slowed down and another measurement value triggers another signal that leads the logical circuits (13) to deactivate both solenoid valves (20, 21) or only the second solenoid valve (21), cutting oil flow to the tilt ram (6).

摘要： A flow control valve is disposed in a bleed-off line which is for returning to a tank a portion of an oil flow advancing toward a hydraulic motor from a hydraulic pump. Upon operation of a control valve in an accelerating direction, the flow control valve is operated in a closing direction with a certain time lag, while upon operation of the control valve in a decelerating direction, the flow control valve is operated in an opening direction without a time lag. By so doing, an accelerating operation can be done smoothly while maintaining a required torque.
