Abstract

1468268 Hydrostatic transmission control EATON CORP 21 March 1974 [26 Sept 1973] 33825/76 Divided out of 1468267 Heading F2W The subject matter of this Specification is identical with that described in Specification 1,468,267, but the claims are directed to reducing the control pressure supplied through the speed control and reversing valve to the pump and motor displacement adjusting servomotors when the delivery from the make-up pump falls below a predetermined value whilst maintaining the original setting of the speed control and reversing valve.
