Abstract
Bypass valve for a hydraulic dashpot, or shock absorber. The valve connects the dashpot's two working compartments together hydraulically and is provided with a valve bolt (1). The valve bolt has a shaft (3) and a hollow adjustment bolt. The adjustment bolt slides back and forth in a stationary and at least partly hollow guide and operates in conjunction with at least one port (8) in the wall of the guide such that the open cross-section of the port can be varied by the axial motion of the adjustment bolt. A mechanism (A) for controlling the axial motion of the adjustment bolt. To minimize strains, the guide is fixed axially and radially and the adjustment bolt is larger than the guide, which accordingly constitutes a pin that the adjustment bolt can slide over axially.
