Abstract: The invention relates to a device (10) for depositing a flowable medium, in particular lubricating oil, onto a workpiece (16). The device (10) has a base body (13) having a duct (14a) for supplying the lubricating oil, the duct (14a) ending in a cavity (14d). The cavity (14d) is covered by a mask (15) having an opening. The opening of the mask (15) is closed by a hard metal sphere (11) which is prestressed into this closure position by a spring (12). When contact is made with a workpiece the sphere is pressed into the cavity (14d) and thereby opens up the opening in the mask (15) for the discharge of lubricating oil.

Abstract: An apparatus for lubricating a surface. The apparatus includes a cylinder having an interior wall extending longitudinally therethrough. The wall defines an opening. The apparatus also includes a lubricating fluid reservoir located upstream from the opening and a path of fluid communication fluidly connecting the reservoir and the opening. The apparatus also includes a valve located in the path of fluid communication. The valve is biased to close the path of fluid communication. At least one valve opening member is disposed in the opening, with the at least one valve opening member operatively connected to the valve. A surface to be lubricated is insertable into the opening such that the surface engages the at least one valve opening member. The at least one valve opening member opens the valve, allowing the fluid to flow downstream from the reservoir, through the path of fluid communication and to the opening to the surface to be lubricated. A method of lubricating the surface is also disclosed.

Abstract: The present invention comprises an oil drain plug apparatus. In one embodiment, the oil drain plug apparatus includes a housing having an opening for receiving a member that moves within the opening between first and second positions. The housing includes a top opening that screwably receives an inlet port of an oil drain plug. The oil drain plug includes an outlet port for mounting to an oil pan of an engine. The housing includes a bottom opening that is substantially aligned with the top opening. The member includes a center opening that is substantially parallel to the top and bottom openings of the housing. When the member is in a first position, the center opening is not aligned with the top and bottom opening, preventing oil from draining from the oil pan. When the member is moved to the second position, the center opening is substantially aligned with the top and bottom openings of the housing, allowing oil to be drained from the oil pan. The member is coupled to a plate.

Abstract: High pressure check valves and fittings, including button head fittings, sealant fittings, and lubrication adapters, that are equipped with dynamically self-centering plungers. Each metallic fitting comprises a fluid inlet and a fluid outlet. The inlet end of each may be configured to be mechanically engaged by high pressure hoses, grease guns, or the like. The outlet end is configured, as by threading, for coupling to the desired application. The inlet and outlet are in fluid flow communication, and meet at an internal valve seat. A steel ball forms the check valve element. The ball is dynamically controlled and centered by a dynamic plunger coaxially and slidably disposed in the fitting. A return spring coaxially mounted on the plunger normally urges the ball and the plunger towards the valve seat to close the fitting. A plunger crown is integral with an elongated, dual-diameter shaft. A conical depression in the crown seats the ball for centering.
