Title: Improvements in or relating to vehicle shock absorbers
IPC: F16F7/04
Filed: 1929-05-09
Abstract: 311,380. Soc. Anon. Ammortizzatori. May 10, 1928, [Convention date]. Vibration-dampers. - Apparatus in which two relatively movable sets of oscillating friction discs operated by arms are pressed together by cams in such a way that the pressure increases steadily as the discs move in either direction away from a central position, is provided with means for adjusting the angular relation between one of the arms and the corresponding cams. In the construction shown in Figs. 3, 7 and 8, arms a and b connected respectively to the frame and axle of a vehicle are formed with discshaped ends pivoted together and separated by discs c of frictional material. Base plates i, n are provided with studs k, w which engage respectively with holes in the outer friction discs on the arms b, a. The plate u engages a square part q on a cone e which is locked frictionally in the socket member d when the nut p is tightened up on the screwed spindle o projecting from the end of the cone e. The nut p then bears on a plate n which engages a shoulder in the socket member d. The angle between the arms a, b where the cams h, g engage may be altered by slacking the nut p and re-engaging the cone e and the socket m which it fits in a new position. The flange f of the socket member d is formed with two diametrically opposed cam grooves g which engage similar projections h on the base plate i. The base plates and discs are forced together by tightening up the nut s on to the end plate y and rubber ring x. When the arms a, b move angularly in either direction away from the position in which the cam projection h and grooves g engage, the projections h ride up on to the flat part of the flange f, thus compressing the rubber ring x and steadily increasing the pressure between the friction members.

Title: Improvements in fluid pressure systems and fluid pressure responsive control valves
IPC: G05D16/06
Filed: 1964-04-08
Abstract: 1,001,739. Regulating Compressors. BENDIX WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. April 8, 1964 [April 12, 1963], No. 14556/64. Heading FIN. [Also in Division F2] in a fluid pressure braking system for use in automotive vehicles, reservoirs 12 and 14 are charged by a compressor 10 via a valve 26 wherein the central portions of diaphragms 60, loaded by light springs 76 acting upon plungers 74, act as check valves to control the one way flow from inlets 24 to outlets 30 connected to the reservoirs and, upon the build up of a pressure differential between the reservoirs e.g. arising from leakage in one of the reservoirs, displacement of a plunger 68 occurs within a bore 64 to abut a plunger 74 and positively obturate flow to isolate from the compressor the reservoir of lower pressure. When a pressure of 100 p.s.i. is attained in either one or both reservoirs and hence in the supply lines thereto a regulating valve 38 opens to permit fluid flow between inlet 40 and outlet 42 in valve 26, via circumferential flutes 78 in bore 64 and, if one of the reservoirs has been sealed off and is not fully charged, fluid flow thereto occurs past the peripheral flange 62 of diaphragm 60 and ports 88 on a guide member 84, which is slidingly received in chamber 56 to act as abutment for springs 80 centering the plunger 68. When the pressure in the bore 64 approaches 100 p.s.i. the plunger 68 assumes a neutral position, and both reservoirs are then charged to 105 p.s.i. whereupon a governor 48 opens to admit pressure to halt the compressor via unloader 46. When pressure on the upstream side of the unloader 48 and the supply lines to the valve 26 falls to 90 p.s.i. the pressure regulating valve 38 closes and, upon a further fall to 85 p.s.i. as one or both reservoirs are supplied past the diaphragm flanges 62 the governor 48 closes and relieves the pressure in the unloader 46 to recommence the compressor. With one reservoir fully charged to 100 p.s.i. and the other depleted below 90 p.s.i. the pressure regulating valve 38 will cycle continuously between closing, due to relieving of pressure on the downstream side to below 90 p.s.i., and opening, as pressure builds up on the upstream side above 100 p.s.i. until either both reservoirs become charged to 105 p.s.i. of the pressure in both reservoir drops to below 90 p.s.i.
