Abstract: A pneumatic spring strut assembly comprises a cylinder comprising a working end and a boosting chamber. The working end includes a first volume of gas and the boosting chamber includes a second volume of gas. A temperature control valve assembly is disposed in the interior volume separating the working end from the boosting chamber and includes an over-pressure valve configured to release the second volume of gas into the working end when the pressure within the boosting chamber increases above the normal pressure range of operation. A valve is disposed in the wall of the cylinder, in the working end thereof, and is configured to yield, to thereby vent the first volume of gas to atmosphere, when the pressure within the interior volume of the working end increases above the normal pressure range of operation.

Abstract: A tube having sealing ring grooves formed by a sequential rotational process and a shock absorber including the tube, in which durability of a sealing ring fitted in each of the sealing ring grooves is enhanced. An inclination angle (θ1) formed with respect to a plane (PL1) perpendicular to an axis of a separator tube by a side surface of the sealing ring groove, which is located on an opening end side of the separator tube, is set to 8° or more. With this, a maximum tensile stress to be applied to an O-ring can be reduced to be smaller than a maximum tensile stress in a case of using a backup ring. As a result, the durability of the O-ring can be set equivalent to or enhanced to be higher than durability in the case of using the backup ring.

Abstract: Provided is a continuous damping control shock absorber of a dual solenoid valve structure. The continuous damping control shock absorber of the dual solenoid valve structure includes a rebound solenoid valve and a compression solenoid valve. In the continuous damping control shock absorber, a separator tube for interworking prevention is installed to form a connection chamber at a position where the rebound separator tube and the compression separator tube are connected, thereby preventing interworking of the rebound solenoid valve and the compression solenoid valve 40. A communication hole is formed in the compression separator tube to communicate with the connection chamber. The separator tube for interworking prevention is configured such that the fluid discharged from the rebound solenoid valve flows into not the low-pressure reservoir chamber but the high-pressure compression chamber during the compression stroke, thereby improving the operational independence of the rebound solenoid valve and the compression solenoid valve. Therefore, it is possible to solve the problem that the compression damping force and the rebound damping force are interworked by the opening of the passage of the rebound solenoid valve during the compression stroke, and to effectively prevent a reduction in the compression damping force.
