Abstract

754,374. Dashpots. E.M.B. CO., Ltd. Feb. 8, 1955 [March 19, 1954], No. 8044/54. Addition to 710,679. Class 108 (3). In a modification of hydraulic control means as claimed in the parent Specification, the cylinder h consists of an angularly adjustable sleeve h<SP>1</SP> having a plurality of ports 5, any one of which can be put into communication with the by-pass j by angular movement of the sleeve, and an additional valve 7 (Fig. 2) for controlling the rate of flow through the by-pass j. The sleeve h is rotatable by the action of a worm 3 meshing with a worm wheel 4 formed on the end of the sleeve h. The ports 5 can thus be rotated symmetrically into register with an axial extension 6 of the intermediate port m. The valve 7 is controllable by manipulation of a handle 8 to vary the area of the flow path from the by-pass j to the reservoir i.
