Abstract

1475206 Rotary positive-displacement fluidmachines TRW Inc 10 Feb 1975 [19 Feb 1974] 5624/75 Heading F1F [Also in Division B7] A controller for use in controlling the flow of hydraulic fluid in the power steering system of a vehicle, is of the kind including a fluid-metering mechanism 12 comprising intermeshing inner and outer gears 54, 50, the controller 10 being characterized in that its torsional coupling assembly 18 coupling the input shaft 16 and the wobble shaft 74 takes the form of one or more resilient blades. In the illustrated embodiment, the torsional coupling assembly 18 comprises a pair of blades 66, 68 which are bowed, as shown in Fig. 4, and which have ends located in a slot 104 of the input shaft 16 and in a slot 122 of the wobble shaft 74. The ends of the blades 66, 68 are formed with protuberances, e.g. the protuberances 156, 164 of Fig. 4, which engage the side walls of the slots 104, 122.
