Abstract: A container system of this invention includes a container for holding a fluid, a follower in the container which moves in the container in response to a change in a level of fluid in the container, and a sensor assembly for sensing the level of fluid in the container. The sensor assembly is especially (albeit not exclusively) suited for viscous fluids.

Abstract: A lubricating system for delivering charges of lubricant and air for aerifying the lubricant to multiple points of lubrication. The system comprises a series of air-operated lubricant injectors each of which is operable in response to delivery thereto of operating air to deliver a charge of lubricant. The injectors are organized in a row in engagement with one another. Each injector has a lubricant passage extending through it, the lubricant passages in the injectors being in end-to-end communication with one another to form a lubricant manifold extending through the row for receiving lubricant and charging the injectors.

Abstract: A cap assembly for covering an injector of a lubricant metering device to sealingly protect the injector from moisture and dirt. The injector has a generally cylindric body and an end structure narrower than the body projecting endwise from the body. The assembly has a cap including a generally cylindric tube having a side wall, an open end, a closed end and a configuration such that the cap is shaped and sized for detachable mounting on the body of the injector in a covering position in which the tube encloses the end structure of the injector. A flexibly resilient gasket has an annular shape with an inner edge sized for surrounding the end structure to enable the gasket to be sealingly secured to the structure and an outer edge sized for engaging an inner surface of the side wall of the cap and forming a fluid-tight seal thereon when the cap is mounted in its covering position.

Abstract: A frangible male coupling component for sealingly coupling a conduit to a fluid delivery device of the type having a female coupling component with a threaded axial passage therethrough and an internal camming surface in the passage. The male coupling component has an integral tubular body of one-piece construction sized to coaxially receive the conduit to be coupled. The tubular body has an axial inner ferrule portion engageable with the camming surface, an axial outer screw portion, and an annular frangible portion integrally connecting the ferrule and screw portions.

Abstract: A hydraulic valve mechanism for a hydraulic motor having a cylinder and a piston reciprocating therein, comprising a valve block having a valve face, a main and an auxiliary central exhaust ports, two main feed ports on opposite sides of the main exhaust port, and two auxiliary feed ports on opposite sides of the auxiliary exhaust port. A valve chest is sealed over the valve face and has aligned piston-receiving bores at its opposite ends, a chamber for pressurized hydraulic fluid between the bores and a valve-actuating piston slideable in the bores. A main D-valve and an auxiliary D-valve operable by the valve-actuating piston move within the chamber in sliding sealing engagement with the valve face. The main D-valve covers and uncovers the main exhaust port and main feed ports to control the reciprocation of the motor piston.
