Title: Transmission for reciprocating motion
IPC: F15B7/00
Filed: 1980-02-11
Abstract: A transmission for reciprocating motion, e.g. to interconnect windscreen wiper shafts on a vehicle, consists of a master 10 and a slave cylinder 11, and interconnecting pipes, both cylinders being double acting. The slave cylinder carries two valves 16, 17, one of which is opened at one end of the stroke and the other at the opposite end, while the other valve of the pair acts as non-return valve, effectively short-circuiting the slave piston and allowing the master piston to travel on to restore synchronism. Another pair of non- return valves 21, 22 is arranged to connect one side only at a time to a reservoir, to make up losses through leakage or thermal contraction, and prevent pressure build-up through thermal expansion. One valve of the second pair may be kept closed when the master cylinder is at the end of its stroke, to prevent the slave cylinder moving back. <IMAGE>
