DEVICE FOR TRANSMITTING A CONTROL FLUID BETWEEN TWO MOVABLE PARTS RELATIVE TO THE OTHER AND APPLICATION TO VEHICLE BRAKING DEVICES, IN PARTICULAR RAIL VEHICLES

摘要

P The two parts 46, 48 are connected to each other by a laminate 40 formed by a stack of layers alternately of rubber 42 and of metal 44 adhering to each other and whose end layers are fixed respectively to the first and to the second part, and the transmission of the control fluid is carried out through a passage 52 which crosses the layers of the laminate and the ends of which are respectively connected to a first pipe 56 integral with the first part and connecting the passage to the source of fluid and a second pipe 54 secured to the second part and connecting the passage to the device for use. The invention is applicable to the supply of control fluid to a rail vehicle brake by means of a rigid pipe 54 carried by the axle support rod and connected by the passage 52 to a supply pipe 56 carried by the bogie. /P
