Abstract
Disclosed is a device for controlling the flow of lubricant oil through an axial passage of a rotating shaft in which the flow of lubricant is not solely dependent upon a nozzle output. The device includes a member extending generally transversely across the axial passage and located downstream of the stationary nozzle. The member has an inner side facing the axial passage and an outer side facing the lubricant nozzle. The member, which also defines an internal cavity, has an intake opening defined through the outer side to enable the oil emanating from the nozzle to pass into the cavity. The member also has a discharge orifice extending through the inner side and communicating with the cavity to enable the lubricant to exit the cavity and enter the axial passage. An evacuation opening is formed through the outer side to control the amount of oil retained in the cavity. The discharge orifice is located a greater radial distance from the center line of the rotating shaft than is the evacuation opening. The location of the evacuation opening acts as a level control for the lubricant within the cavity.
