An assembly (AS1) in accordance with the subject matter of the present disclosure can include a gas spring (200), an internally-mounted device (300) and a mounting assembly (400, 500) operatively connecting the internally-mounted device to an end member (202, 204) of the gas spring (200). The mounting assembly (400, 500) can permit at least a portion of the internally-mounted device to undergo 360 degree rotational and pivotal displacement relative the end member (202, 204) of the as spring (200). The mounting assembly (400, 500) can include a device mount (402, 502) that can be operatively secured to the internally-mounted device (300) and a retainer (404, 504) that is secured to the end member (202, 204) and operatively retains the device mount (402, 502) adjacent the end member (202, 204). The device mount (402, 502) and the retainer (404, 504) can include complimentary semi-spherical surfaces that permit the relative movement between internally-mounted device (300) and the end member (202, 204) of the gas spring (200).

A hydraulic pressure cushioning device includes: a cylinder; a rod movably provided in the cylinder; a first piston valve section that is provided on the rod. The first piston valve section includes: a first piston member and a second piston member that form a channel; and a single first damping valve with which a first flow of the fluid from the first side to the second side in the channel and a second flow of the fluid from the second side to the first side in the channel are controlled; a bypass path which differs from the channel; and a free piston provided on the rod in such a manner that a flow of the fluid is switched between the channel and the bypass path in accordance with a movement position of the rod.

A sealing structure with a torsional damper and an oil seal includes a damper pulley serving as a torsional damper and an oil seal.
