A hydraulic shock absorber includes a piston, a damper tube, a suspension spring, a plunger, a jack chamber, a pump case, a pump piston, a screw shaft, and a drive unit. Both end surfaces of the pump piston in a reciprocating direction are a first end surface demarcating the pump chamber, and a second end surface demarcating the gas chamber, the second end surface having a screw hole into which the screw shaft is screwed. The pump piston includes a space portion between a bottom plate defining the first end surface and the screw hole. The screw shaft has a through-hole connecting the gas chamber with the space portion.

A shock absorber for a vehicle includes a damper tube defining a valving piston chamber that contains a hydraulic fluid. The shock absorber further includes a piston rod extending within the damper tube along a first longitudinal axis, and a valving piston assembly slidably fitted in the damper tube. The shock absorber further includes a seat tube disposed in fluid communication with the valving piston chamber and defining a seat piston chamber therein. The shock absorber further includes a seat piston slidably fitted at least partially in the seat tube. The seat piston is configured to move along a second longitudinal axis relative to the seat tube based on a pressure of the hydraulic fluid within the seat tube.

In a vehicle suspension, a preload is adjusted by selective engagement of cam surfaces of different heights with a cam receiving part by rotation of an adjuster part, the adjuster part includes a vertical wall part erected in an axial direction of a spring from a spring receiving part and an engaging part with which a tool to rotate the adjuster part is to be engaged, and the engaging part includes a first engaging part formed by a gap between the plurality of vertical wall parts disposed separately from each other in a circumferential direction of the adjuster part and a second engaging part formed by a hole penetrating the vertical wall part.

The present disclosure relates to a steering stabilizer for a vehicle. The stabilizer has a damper having a housing, a piston rod extending telescopically from the housing, and a coil spring disposed over the damper. An inner adapter assembly secures a first end of the damper to one of a wheel component or a body component of the vehicle. An outer adapter assembly is coupled to a distal end of the piston rod and couples to the other one of the wheel or body component. A one-piece spring seat is fixedly coupled to the housing. The coil spring is supported at a first end by the spring seat and at a second end by the outer adapter assembly. The spring seat enables the single coil spring to return the steering stabilizer to a central position regardless of whether the single coil spring is under tension or compression.

A drape includes a first drape portion configured to receive a manipulator arm of a surgical system and a pocket coupled to a distal portion of the first drape portion. The pocket is configured to receive a manipulator of the surgical system. The pocket includes a flexible membrane positionable between an output of the manipulator and an input of a surgical instrument mountable to the manipulator. In some embodiments, the flexible membrane is located at a distal end of the pocket. In some embodiments, the flexible membrane is configured to allow an actuating force to be transmitted from the output of the manipulator to the input of the surgical instrument. In some embodiments, the pocket provides a sterile barrier between the manipulator and the surgical instrument. In some embodiments, the drape further includes a rotatable seal configured to couple a proximal opening of the pocket to the first drape portion.

A flow path control device according to one embodiment includes a first valve, a unit main body and a control valve. The unit main body has an accommodation portion, a first radial communication hole and a side recess portion. The accommodation portion is recessed from a chamber accommodating the oil to cause the first valve to close the first radial communication hole. The side recess portion is recessed from the chamber so as to be continuous to the accommodation portion and not to be continuous to the first radial communication hole. The control valve is movable in the accommodation portion of the unit main body between a position at which a groove of the control valve communicates with the side recess portion and the first radial communication hole and a position at which the groove does not communicate with them.

A vehicle height adjustment apparatus according to one embodiment include a spring, a spring-length changing unit, a first valve, a control valve and a second valve. The spring-length changing unit changes a length of the spring in accordance with an amount of oil in a jack chamber that accommodates the oil. The first valve opens and closes a first communication path in which the oil supplied from a pump is oriented toward a reservoir chamber that stores the oil. The control valve opens and closes a discharge flow path oriented toward the reservoir chamber from a chamber that accommodates the oil to close the first valve. The second valve opens and closes a second communication path in which the oil supplied from the pump is oriented toward the jack chamber when the first valve is closed.

A vehicle height adjustment device includes a changer, a detector, and a controller. The changer is configured to change a relative position of a body of a vehicle to an axle of a wheel of the vehicle. The detector is configured to detect the relative position. The controller is configured to control the changer to change the relative position based on a detection value detected by the detector so as to control a height of the body as a vehicle height. The controller is configured to control the changer to maintain the vehicle height when there is a possibility of a malfunction in the detector.

A wrench and nut combination, including: a wrench lug including: a wrench lug feature that substantially mates with a nut feature of a nut of a shock absorber during a first rotation of said nut, relative to external body threads on a body of the shock absorber, in a first direction, wherein the wrench lug feature and the nut feature release during a second rotation of said nut, relative to the external body threads, in a second direction, wherein at least one of the first rotation and the second rotation causes an adjustment to a compressive coil spring pre-load of a set of coil springs disposed in the shock absorber.

A vehicle height adjustment device includes a changer and a controller. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The controller is configured to control the changer to make the relative position a target value so as to control a vehicle height of the body. The controller is configured to control the changer to maintain the relative position when there is a possibility of a malfunction in a detector configured to detect a parameter for control.
