A transmission for use in the power train of a motor vehicle has a rotary first component (such as a shaft), a second component which may but need not be rotatable, a fluid-conveying conduit having a first end portion extending into a first socket provided in the first component and a second end portion extending into a socket of the second component, a split-ring piston packing located in an external groove of the first end portion, and an O-ring received in an external groove of the second end portion. The O-ring prevents the conduit and the second component from rotating relative to each other. A passage which is defined by the two components and the conduit can receive a stream of pressurized hydraulic fluid from a pump by way of pipes wherein the flow of fluid is controlled by several valves including a manually operated slide valve, at least one preferably adjustable pressure regulating valve, at least one preferably adjustable safety valve, and adjusting means for the adjustable valve or valves; such adjusting means can employ one or more signal-responsive control valves.

1. A fluid conveying structure, comprising:a first component having a first socket; a second component having a second socket; a conduit having a first end portion disposed in said first socket and a second end portion disposed in said second socket; at least one first sealing element interposed between said first component and said first end portion in said first socket, said first component and said first end portion in fitting contact with one another so as to permit said first component and said first end portion to be freely rotatable relative to each other; and at least one second sealing element interposed between said second component and said second end portion in said second socket; and said first end portion having a first end face and said second end portion having a second end face, the area of the first end face being greater than the area of the second end face, wherein said components and said conduit are rotatable about a common axis, and further comprising means for rotating said first component at a first speed n1, and means for rotating said second component at a speed n2 less than said first speed.
