One aspect of this disclosure is directed to a Steering system comprising a housing in inch a steering rack is movably arranged and extends out of the housing on at least one side of the housing with a steering rack end portion. The steering rack being connected to a tie rod with a ball joint. At least the sections of the steering rack extending outside of the housing and the ball joint are covered by at least a protective bellows defining a central axis and the bellows further comprising a first bellows end defining a first bellows opening around the central axis and a second bellows end defining a second bellows opening around the central axis. The bellows is arranged inside a puncture resistant cover. The cover comprises a first cover end defining a first cover opening around the central axis and a second cover end defining a second cover opening around the central axis. At least one of the cover ends comprises at least one loop at least partially extending around the least one cover end and in which loop a clamp to fasten the cover end is arranged. The first bellows end and the second bellows end are arranged between the first cover end and the second end. Another aspect of this disclosure is directed to a puncture resistant cover with an elongated tubular shape along a central axis. The cover comprises a first cover end defining a first cover opening around the central axis and a second cover end defining a second cover opening around the central axis. At least one of the cover ends comprises at least one loop at least partially extending around the least one cover end and in which loop a clamp to fasten the cover end is arranged.

A bi-level tank includes a transfer tank and a return tank containing a volume of water, including transfer and return components in the transfer and return tanks, respectively, and a transition component. A bellows couples an upper surface of a piston in the transfer tank to the return component that exerts pressure on the upper surface, while a lower surface of the piston is under pressure from a pressured fluid supplied by a source thereof, producing a pressure differential on the piston. Actuation of a force-applying mechanism on the piston sufficient to overcome the pressure differential displaces the piston for exchanging respective volumes of the return component and the fluid from the source. An extensible and retractable constant-volume boot holds the transition component around the bellows and has valves configured to open and close for equalizing pressure between the boot and the transfer tank.

A dust cover and a sealing structure for improving sealing performance by stabilizing a posture of a seal section. A seal section 130 includes: an inner peripheral seal part 131 which is slidable with respect to an outer peripheral surface of a shaft part 310; a dust lip part 132 which is slidable with respect to an end surface of a first flange part 340; and an auxiliary dust lip part 133 provided on an radially inner side of the dust lip part 132, and the auxiliary dust lip part 133 is configured to be slidable with respect to a curved surface 310a which connects the shaft part 310 and the first flange part 340 to each other.

In at least some implementations, a constant velocity joint includes a first rotational member and a boot can assembly coupled to the first rotational member. The boot can assembly includes a boot can, a boot and a seal carried by the boot can and arranged to engage and seal against the first rotational member when the boot can assembly is coupled to the first rotational member. The boot and seal may be formed from the same piece of material and may be bonded to the boot can. The boot and seal may be overmolded onto the boot can.
