    摘要: A flow control valve apparatus includes a housing including a main fluid passage having an inlet port and an outlet port; a main valve disposed between the inlet port and the outlet port for allowing or shutting off communication between the inlet port and the outlet port; a backpressure chamber formed between an inner wall of the housing and a rear portion of a valve member of the main valve, the backpressure chamber communicating with the inlet port through an orifice; an auxiliary passage for placing the backpressure chamber in communication with the outlet port; and a pivot valve for actuating the main valve by controlling the opening and closing of the auxiliary passage and varying the fluid pressure in the backpressure chamber. A differential pressure generating means is disposed in the main fluid passage for generating differential pressures that correspond to the flow rate in the main fluid passage. The differential generating means includes a displacement member disposed for movement in the direction in which a fluid flows in the main fluid passage and spring means for urging the displacement member in the direction opposite to the direction in which the fluid flows, and the displacement member cooperates with a wall surface of the main fluid passage to define a fluid passage having an opening area which increases in accordance with an increase in the stroke of travel of the displacement member.

    摘要: A flow control system is arranged in a hydraulic circuit provided with a variable displacement hydraulic pump, plural actuators and a pump controller. The pump controller controls the displacement of the pump so that a delivery pressure becomes higher by a predetermined value than a maximum load pressure of the plural actuators, whereby the flow rate of pressure oil to the actuators is controlled. The system includes plural valve units connected between the pump and the actuators. Each valve unit has an operating and correcting variable restrictors. The system also includes pressure compensation valves, which are each arranged on an upstream side of a restrictor group consisting of the operating and correcting variable restrictors. The opening of the pressure compensation valve is independently set by an opening drive force set based on a downstream pressure of the restrictor group, an opening drive force set by a pressure-difference setting device and a closing drive force set based on an upstream pressure of the restrictor group so that the upstream pressure becomes higher by a predetermined pressure than the downstream pressure of the restrictor group.

    摘要: [Problem]To prevent an eccentric load from occurring in a nut member of a linear actuator and ensure a longer service life of the nut member.[Solution]The nut member is coupled to a driven member by a contact force equalizing mechanism having two rotation axes which are virtually perpendicular to each other, to absorb slight inclination between the nut member and the driven member and prevent occurrence of an edge load; also the point of intersection which is obtained when the two rotation axes are projected toward a threaded shaft is set as an optimum point of application of load for the nut member to let an external force transmitted from the driven member act on the optimum point of application of load to equalize the loads applied to the contact portions between the nut member and the threaded shaft and thereby prevent an eccentric load from occurring in the nut member.

    摘要: This invention relates to a fault diagnosis system for hydraulic pumps in a work vehicle, which is economical and permits sure identification of one or more trouble-developed ones of the hydraulic pumps.Pressure sensors 61-64 are arranged on pressurized fluid lines 30,40, which extend to a tank T from points immediately out of center bypasses of flow control valves 21,231-234,451-454,26 communicated to hydraulic pumps 1-6. Solenoid-operated directional control valves 51-56 are interposed in input circuits of individual regulators 11-16 so that, upon excitation, a pressure of a pilot pump 7 is introduced into the regulators 11-16. When all the flow control valves are brought into neutral positions thereof and a determination is instructed through a switch 80, one of the solenoid-operated directional control valves is excited by a signal from a processor 70 so that pressurized fluid is delivered at a maximum flow rate from the corresponding hydraulic pump. A detection value of the corresponding pressure sensor at this time is translated into a flow rate, which is then stored. These procedures are performed with respect to the individual hydraulic pumps successively. Based on a flow rate obtained in every determination, a fault diagnosis of the corresponding particular hydraulic pump is performed.
