摘要： In preferred form, a direct acting hydraulic shock absorber with auxiliary passages between the working chambers of the shock absorber and the reservoir chamber controlled by a thermally responsive valve which blocks fluid flow upon sensing a predetermined fluid temperature. An annular channel formed about the pressure cylinder of the shock absorber has a wall portion spaced radially outward from openings in the pressure cylinder and has openings to the reservoir chamber. A cylindrical ring valve in the annular channel is spaced inwardly from the wall portion when it is below the predetermined temperature. The ring valve expands outwardly against the wall portion to block the auxiliary passages to the reservoir chamber when above the predetermined temperature.
