Abstract: A liquid filter, particularly for the lubricating oil of an internal combustion engine, having at least one replaceable filter and a carrier module, in which the replaceable filter has a housing with an inlet and an outlet for the liquid to be filtered; a housing vessel with an opening pointing essentially downward is provided, and a filter medium is arranged in the housing between the inlet and outlet in a sealed manner. The replaceable filter with the opening pointing downward is attached in a sealed manner to the carrier module, and the carrier module has semiautomatic emptying device for the replaceable filter such that emptying of the replaceable filter is initiated by an external operation which opens a drain passage, and the drain passage is automatically closed again after the emptying process is completed.

Abstract: A line strainer for screening fluid flow in a small diameter conduit is constructed with an integral housing of clear or transparent thermoplastic polymer. A fluid flow channel through the housing center is terminated at opposite ends by sonically welded end fittings. Internally of the housing, a screen chamber is separated from a flow meter chamber by a screen support hub with flow diversion passages. The screen chamber confines a conically formed screen mesh for passing substantially all flow through the housing. The flow meter chamber has conically tapered walls that support radial fins projecting from the walls inwardly to a cylindrical void that confines the metering ball to displacement along the housing axis. A spring bearing against the metering ball resiliently biases the ball toward the flow restriction passage and against the fluid flow direction. The spring bias and conically tapered meter walls cooperate with the flow stream and metering ball to stabilize at a position along the housing axis that is proportional to the flow rate through the screen. As the screen mesh fills to increase flow stream resistance, the metering ball approaches the flow restriction passage signaling a reduced flow rate. The degree of plugging or filling of the screen mesh is therefore indicated by the relative position of the metering ball for a substantially constant pressure source. Additionally, pump performance or system blockage could also be detected by the ball position in the flow meter chamber.

Abstract: A spin-on filter assembly for filtering engine coolant has a transparent plastic container attached to a cover plate by an annular joint. The annular joint is formed by an annular trough in the cover plate, which annular trough has a lip which overlies a radial flange on the transparent plastic container. A filter element is disposed within the container and is urged by a coil spring against an end plate which abuts the cover plate. The end plate has a threaded central outlet opening and a plurality of spaced inlet openings which are accessed through a recess in the cover plate. The spin-on filter assembly is mounted in the coolant system of an internal combustion engine by a hollow threaded stud.
