Abstract: A control valve apparatus includes a second-working-actuator acceleration control valve connected to a first working control valve in parallel. The second-working-actuator acceleration control valve includes pilot chambers receiving a pilot pressure for switching first and second working control valves and a flow channel that guides a pressure fluid of a first pump port to an entrance port side of the second working control valve. The second-working-actuator acceleration control valve is switchable between a first priority position in which a pressure fluid is guided to the first working control valve with a higher priority than the second working control valve and a second priority position in which a pressure fluid is guided to the second working control valve with a higher priority than the first working control valve.

Abstract: A solenoid valve includes a housing having a cylindrical shape and having a valve path, a spool adjusting an opening degree of the valve path, a coil producing a magnetic force when a current passes therethrough, a first and a second stator core excited by the magnetic force of the coil, a shaft configured to be movable along axial direction together with the spool, a plunger fixed to the shaft and moving in the axial direction by adsorption force acting between itself and the first stator core by the magnetic force of the coil, and a coil spring biasing the spool against the adsorption force acting on the plunger. A spring constant of the coil spring increases as the adsorption force increases by the movement of the plunger.

Abstract: A damper includes a cylinder, an annular rod guide, an annular seat, a rod, an annular oil seal, a rebound cushion, and a communication passage. The cylinder houses an action chamber. The rod guide is secured to one side opening of the cylinder. The seat is secured to the rod guide. The rod is inserted through inner peripheral sides of the rod guide and the seat. The oil seal is held to an inner periphery of the rod guide and slidably in contact with an outer peripheral surface of the rod. The rebound cushion bumps against the seat. The communication passage transmits a pressure in the action chamber to the oil seal. An opening on the communication passage on the action chamber side is disposed on an outer peripheral side relative to a part of the seat against which the rebound cushion bumps.
