摘要： A machine has a first member, a second member, a bearing, and a spring. The bearing inner race is mounted to the second member. A spring first end portion is mounted to the first member. The bearing outer race is mounted to a spring second end portion. The spring has a flexible portion between the first end portion and the second end portion. A first annular seal is carried by an outer diameter first groove in an outer diameter surface of the second end portion and seals with an inner diameter surface of a sealing portion of the first member. A second annular seal carried by an inner diameter second groove in the first member and seals with an outer diameter surface of the second end portion. A fluid outlet in the first member opens to a chamber between the first annular seal and the second annular seal.

摘要： An oil nozzle assembly includes a nozzle body and a nozzle insert. The nozzle body includes a main portion, a tip portion, a collar, and a lip. The tip portion is connected to the main portion. The collar is positioned at an interface between the main portion and the tip portion. The lip extends radially outward from the tip portion and includes an outer diameter. The nozzle insert includes a sleeve, an endwall connected to the sleeve, an orifice, and a retention element. The orifice is disposed in the endwall and is fluidly connected to the tip portion of the nozzle body. The retention element extends radially inward from the sleeve. A portion of the retention element includes an inner diameter that is less than the outer diameter of the lip.
