Abstract
764,927. Hydraulic brakes. STANDARDTHOMSON CORPORATION. Oct. 14, 1954 [Nov. 18, 1953], No. 2960/54. Class 103 (1). [Also in Groups XIII and XXIX] An hydraulically-operated mechanical transducer, which has possible application to braking devices, comprises a two-part cylinder 2, 4 enclosing a space 24 which is closed at one end by a flexible seal 20 surrounded by a substantially incompressible but deformable support member 22 and having on its outer cylindrical surface a metal sheathing 14 consisting of woven helically-wound strands, each strand preferably consisting of a number of filaments, either parallel, twisted or braided to one another. One end of the sheathing 14 is secured to the sleeve 2 at 16 by welding or soldering or the like, the other end being similarly secured to a movable plate 18 adapted to bear against the inner end of a piston 8. It is shown mathematically that according as to whether the braid angle # is greater or less than a critical value between 54 and 55 degrees so an increase in the volume of space 24 will cause a lengthening or a shortening of the sheath. Thus by filling space 24 with a suitable thermal material, such as wax, or by increasing the pressure from a remote source of pressure such as a thermal bulb 40 the device can be made to expand or contract, thus moving a member 10 which is to be actuated.
