Abstract: A pre-oiling system for automatically injecting oil into the oil gallery lubricating system of an automotive engine prior to start up. The assembly includes an outer vessel, a manifold valve block, which is attached to the outer vessel and includes a solenoid valve, and a control circuit for logic control of the solenoid valve. An air replenishment assembly is positioned on the outer vessel permitting measurement of the pressure in the outer vessel and also allowing for air to be added to the outer vessel to pressurize oil contained within the outer vessel. In one embodiment, the air replenishment assembly includes a schrader valve which provides replacement air to the outer vessel and the spare tire. Oil is automatically injected into the oil gallery lubricating system upon the engine starting. Specifically, the solenoid valve is opened in response to the engine being started which allows pressurized oil to flow from the outer vessel to the oil gallery of the engine.

Abstract: A bearing assembly (22, FIG. 4 ) is provided for connecting an actuator (14A) to a shake table (12) on which a test object is mounted, which minimizes the mass to be moved by the actuator. The bearing assembly is of the type that includes upper and lower spherical bearings (30, 32) that each has inner and outer spherical members (36, 38 and 40, 42), an outside transmit member (54) which couples the outer members, and a shaft (70) which couples the inner members. The inner members are formed of a more rigid material such as steel, than the outer members which are formed of aluminum, for more closely equalized deflection of the engaged members at high loads. The shaft has an upper end (72) which is fastened to and projects above the inner member of the upper spherical bearing, and that lies in a recess (90) formed in the underside of the shake table.
