An oil jet assembly includes a body, a tube, a cap insert, a ball, and a spring. The body includes a bore passing longitudinally through the body; a tube aperture passing through the body near a first end of the body; and an opening at a second and opposite end of the body. The tube is attached to the body and in fluid communication with the tube aperture. The cap insert is positioned within the bore of the body. The cap insert includes a bore that passes longitudinally through the cap insert to form a wall. The cap insert also includes an oil exit aperture passing though the wall and is in fluid communication with the bore of the body. The ball and spring are positioned within the bore of the insert cap. The spring is positioned between the ball and the first end of the body.

A fluid jet for providing fluid under pressure to a desired location is disclosed wherein the valve body includes and integral valve element retaining region. Preferably, the valve body and integral valve element retaining region are die cast as a one-piece component. More specifically, the fluid jet includes a die cast one-piece valve body having a valve element retaining region extending longitudinally within at least a portion of the valve body, at least one fluid passage extending longitudinally within at least a portion of the valve body and in fluid communication with at least a portion of the valve element retaining region, and at least one fluid-exiting aperture through the valve body in fluid communication with the at least one fluid passage.

Bearing caps and methods for manufacturing bearing cap are disclosed. Bearing cap includes a body that comprises an abutment surface, a bearing surface, an exterior surface, and a recess portion. The abutment surface provides for the bearing cap to be coupled to an engine along a flat and even surface. The bearing surface provides for the bearing cap to at least partially capture the bearing shaft to secure the bearing shaft when the bearing cap is abutted to the engine. The recess portion extends into the body of the bearing cap from the exterior surface to reduce the weight of the bearing cap. The recess portion can be located anywhere along the exterior surface and be any shape and dimension that retains sufficient structural integrity of the bearing cap to secure the balance shaft to the engine.

Pressure actuated oil jets have long been used to cool the underside of the pistons in such reciprocating engines. The present disclosure is a fluid jet for providing fluid under pressure to a desired location. The fluid jet comprises a valve body, at least one fluid passage extending longitudinally within at least a portion of the valve body, a fluid pressure actuated valve element located within the valve body and moveable longitudinally therein between a valve open position and a valve closed position, and a sleeve extending inwardly within said valve body, wherein said valve element is retained within said sleeve when oil pressure drops below a predetermined threshold.
