Abstract

1395940 Master cylinders; brake actuators GIRLING Ltd 29 Oct 1973 [22 Nov 1972] 54072/72 Heading F2F An hydraulic piston and cylinder assembly such as a brake master cylinder or wheel cylinder in which the piston is urged in one direction by a spring has the spring 9 at least partially accommodated within a longitudinally extending recess or blind bore 18, in at least one of the members and a plunger 19 displaces fluid from the recess or bore upon relative movement towards each other of the plunger and member containing the recess. In a wheel cylinder, Fig. 2, opposed pistons 32, 33 have blind bores 35, 36 containing a spring 34 and plunger 37. A single cylinder, Fig. 3, has the bore 31 closed by an end wall 40, a flange 38 on the plunger being urged against the wall 40.
