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： A device includes an outer cylinder having a cylinder inner wall and a cylinder outer wall and at least one magnet disposed on or between the cylinder inner wall and the cylinder outer wall and a piston having a piston inner wall and a piston outer wall and at least one magnet disposed on or between the piston outer wall and the piston inner wall. In one embodiment, the piston is rotatable within the cylinder and slidably movable along an axis respective to the cylinder. The piston is also disposed within the cylinder such that the at least one magnet disposed on or between the cylinder inner wall and the cylinder outer wall is aligned with the at least one magnet disposed on or between the piston outer wall and the piston inner wall, substantially preventing the piston from rotating relative to the cylinder.

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).
