An electromechanical actuator (100) is provided. The actuator comprises an electrical motor (110) controlling a ball ramp mechanism. The ball ramp mechanism is configured to allow for mutual rotation of a first and second rotational member (120, 30) up to a first torque of the electrical motor (110), and to allow for axial separation of the first and second rotational members (120, 130) at a second torque of the electrical motor (110).

An actuator is used to longitudinally move a spline sleeve for controlling drive mode of a differential on an off-road vehicle. The actuator's motor rotates an eccentric knob through a drive train including intermediate gears and a worm gear. The eccentic knob is linked to the spline sleeve through a torsion spring carried on a pivot plate, with legs of the torsion spring pushing a slide block, transferring a moment provided by the eccentric knob into a linear slide force. The pivot plate and torsion spring are jointly mounted on the actuator housing by a hub, opposite the rotational axis of the eccentric knob from the slide block. The slide block includes a contact which completes a circuit through conductive pads on the actuator housing, so the position of the slide block can be directly sensed.

An evaporated fuel processing device includes a relationship learning unit that, during a learning operation, learns the relationship between a valve opening start amount and a pressure difference. In particular, the relationship learning unit learns this relationship when a valve opening detection unit detects a plurality of different valve opening start amounts and a pressure difference detection unit detects a plurality of different pressure differences. Then, the relationship learning unit creates a relationship map between the valve opening start amount and the pressure difference. The evaporated fuel processing device then corrects the valve opening start amount based on this relationship map.

A valve guide moves back and forth relative to a housing. A valve engages with and slides on the valve guide to open and close a sealing passage of the housing. A valve-side spring is sandwiched between the valve guide and the valve and biases the valve. The valve-side spring has an outer wire portion defining a flat surface at a distal end in an axial direction and that is orthogonal to the axial direction. A pitch between the outer wire portion and an adjacent wire portion adjacent to the outer wire portion is smaller than a pitch between regular wire portions in at least one end of the valve-side spring in the axial direction. The outer wire portion and the adjacent strand portion are in line contact with each other in a circumferential direction.

This disclosure is directed to vehicle fuel systems that include door opening modules for controlling a fuel door opening sequence. An exemplary door opening module may include an actuator (e.g., a motor, an electromagnet, a solenoid, etc.) for automatically moving the fuel door to an ajar position after a fuel tank depressurization sequence is completed. Sound messages may be communicated to a user during the depressurization sequence by an audio actuator.

A lid opening and closing device for a vehicle which includes a restriction member that can operate between a restriction position at which movement of a rod at the lid closed position is restricted and a restriction release position at which the restriction is released, an electric motor that operates for a predetermined time in response to a door switching between a locked state and an unlocked state for driving the restriction member, and a case that houses the restriction member and the electric motor, wherein at least the restriction release position of the restriction member is resiliently held by a holding mechanism. Thus, even when the restriction member stops at position halfway between the restriction release position and the restriction position, convenience is enhanced by carrying out an operation of locking the door by moving the rod to the lid closed position without requiring an unlocking operation.

A disconnect assembly, including: a selector; a first clutch including a first sleeve; and a second clutch including a second sleeve. In a drive mode, the first sleeve non-rotatably connects a first drive gear and a first axle of a first drive train, and the second sleeve is non-rotatably connects a second drive gear to a second axle of a second drive train. In a disconnect mode, relative rotation between the first drive gear and the first axle is enabled and relative rotation between the second drive gear and the second axle is enabled. To transition from the drive mode to the disconnect mode, the selector is displaced by an actuator, the selector is arranged to disconnect the first annular sleeve from the first drive gear or the first axle, and the selector is arranged to disconnect the second annular sleeve from the second drive gear or the second axle.
