ABSTRACT:
A lubricating oil flow control device, especially for a speed change transmission operating in an oil bath, has a clutch actuator which is shiftable along the periphery of a shaft provided with an oil passage individual to the clutch or operating the latter. This actuating plate has an axially extending sleeve which obstructs a radial bore in the shaft in the unactuated position of the clutch and thereby limits the flow of oil to the clutch plate or lamella. In another operating position of the actuating plate, the bore is unobstructed and provides, e.g. via holes in the sleeve and in a sleeve of a gear to which the clutch can connect the shaft, a substantially direct flow path to the center of the clutch in an unobstructed manner.
