    摘要: A hydraulic device comprises a base member, a piston, a seal ring, and an intermediate member. The base member includes a cylinder bore and an annular groove. The annular groove includes a first inner surface and a second inner surface. The piston is movable relative to the base member from a rest position toward an actuated position in a second direction opposite to a first direction. The piston is movable relative to the base member from the actuated position toward the rest position in the first direction. The seal ring includes a first axial surface facing in the first direction and a second axial surface facing in the second direction. The seal ring is provided in the annular groove so as to define a clearance between the first axial surface and the first inner surface. The intermediate member is provided in the clearance.

    摘要: Disclosed are lock mechanisms for latch assemblies of vehicle compartment hoods, methods for making or using such lock mechanisms, and motor vehicles equipped with a multi-pull latch and lock system for releasably locking a hood assembly. A lock mechanism includes a gear that couples a closure latch to a latch release mechanism. The gear moves between a latched position, whereat the closure latch secures the closure in a closed position, and an unlatched position, whereat the gear transfers activation forces from the release mechanism to disengage the closure latch from the closure. A pawl is movable between a locked position, whereat the pawl engages and locks the gear in the latched position, and an unlocked position, whereat the pawl disengages the gear. An actuator is operatively engaged with a vehicle door to automatically move the pawl to the unlocked position responsive to movement of the door to an open position.

    摘要: An output rod (27) is inserted in a housing (4) so as to be movable vertically. A first piston (41) inserted in a lower part of the housing (4) is fixed to the output rod (27). A second piston (42) inserted on an upper side of the first piston (41) is fitted on the output rod (27) so as to be movable vertically. A lock chamber (44) is provided between the first piston (41) and the second piston (42). A first release chamber (51) is provided below the first piston (41). A second release chamber (52) is provided above the second piston (42). During force multiplication driving of the output rod (27), a pressurized fluid in the lock chamber (44) carries out the force multiplication driving with respect to the output rod (27) downward via the second piston (42) and engaging balls (69). A retaining spring (60) which biases the second piston (42) upward is provided in the lock chamber (44) between the first piston (41) and the second piston (42).

    摘要: An object of the present invention is to provide a fluid pressure cylinder improved in assembling performance so as to easily fix a partition wall to a cylinder main body. A plurality of pistons 15a and 15b are incorporated in a cylinder main body 11, axially aligned with each other, reciprocable in an axial direction, and respectively provided with piston rods 17a and 17b. A partition wall 14 is attached to the cylinder main body 11 so as to form pressure chambers 21a and 21b. A stopper space is formed by an engagement groove 31 provided to the partition wall 14 and a slit 32 formed so as to extend in a transverse direction of the cylinder main body 11. A stopper 34 is inserted in the stopper space in the transverse direction of the cylinder main body 11 so as to fix the partition wall 14 to the cylinder main body 11.
