Abstract: A filter assembly employs a base which mounts a disposable filter element cartridge. The cartridge includes either a single stage or a dual stage filter system. The base has custom and generic structural members. Variations in base design are accommodated in the custom member, the generic member having a generic design. The custom member is molded from polymeric material and requires no additional machining or treatment prior to use. This eliminates filter model specific shop fixtures and gigs, reducing costs and providing greater flexibility.

Abstract: A filter assembly employs a bracket and a base which mounts a disposable filter element cartridge. The bracket has a bracket mounting portion for mounting the bracket to a vehicle and a base mounting portion for mounting the base. The bracket mounting portion may be offset from the base mounting portion to provide mounting flexibility. The base mounting portion has a plurality of outwardly projecting catches that engage and support a corresponding number of hangers on the base. A threaded stud mounted on the bracket is received between the hangers. A nut in threaded engagement with the stud is torqued into engagement with the base, securing the base to the bracket.

Abstract: A fuel filter assembly employs a base which mounts a disposable filter cartridge. A pair of axial conduits provide fluid communication between the base and the cartridge. An orifice located in one of the conduits provides a bleed vent which controls the formation of air bubbles in filtered fuel exiting the fuel filter.

Abstract: A fuel injection pump having a fixed pump body with a pumping chamber having a plurality of plunger bores, a plunger mounted in each plunger bore for reciprocation, a cam rotatable for reciprocating the plungers to periodically supply an intake charge of fuel to the pumping chamber and deliver a high pressure charge of fuel from the pumping chamber for fuel injection and to sequentially position the plungers in distributor valve positions thereof to deliver the high pressure charges of fuel, via distributor ports in the plunger bores, to a plurality of distributor outlets. In one version of the pump, the plunger bores are angularly spaced about and extend radially inwardly to a central coaxial bore, the rotary cam is an annular cam which actuates the plungers inwardly to deliver the high pressure charges of fuel, and a poppet valve is mounted in the central coaxial bore to supply fuel to and spill fuel from the pumping chamber.

Abstract: A fuel filter assembly of a type wherein a disposable cartridge element is suspended below a base is adapted so that cartridge replacement may be accomplished in a dry or spill-free fashion. A plug is dimensioned and positioned within the base and extends into the mounted cartridge to occupy a pre-established cartridge volume. When the cartridge is axially dismounted from the base, the cartridge essentially gains free volume. The free volume gain allows for the cartridge to capture any fuel which may drain from the base.

Abstract: A fuel filter assembly employs a spring-loaded collar which retains the disposable cartridge to the base. The collar carries a wave spring and comprises followers which ascend a spiral ramp of the base for securing the disposable cartridge to the base in a positive locked position. The filter assembly also incorporates an efficient bleed orifice and a pair of axial spaced seal rings for implementing a fluid seal with the received disposable cartridge.

Abstract: A plug is adapted for sealing a disposable filter cartridge. The plug is inserted into the axial opening of the cartridge for temporary retention by the grommet. The plug is then reversed and inserted into the grommet of the spent filter cartridge for sealing the contents. The plug is constructed to resist removal from the spent cartridge. A second plug embodiment seals with a sleeve-like grommet at two axial spaced positions.

Abstract: A fuel injection system having a fuel injection pump with an electrical control valve for controlling the fuel injection timing and quantity, an electrical control unit (ECU) for storing certain data, including certain master calibration data, for regulating the operation of the control valve, a pump mounted, electrical module having a male connector for connecting the pump mounted module to the ECU, and a printed circuit board mounted on the male connector pins, the printed circuit board having a calibration resistor for establishing an electrical calibration value at one of the pins for adjusting the master calibration table for adjusting the fuel injection quantity.

Abstract: A fuel filter assembly incorporates a modular drain bowl which may be removably mounted at the lower end of the disposable filter cartridge. An anchor insert is disposed interiorly at the lower portion of the cartridge sump for anchoring a fastener to attach the drain bowl. The insert also is specially configured to form outlet passages which facilitate the flow of water from the sump to the drain bowl.

Abstract: A fuel injection pump having a rotor with a distributor rotor at its outer end and an annular arrangement of radial pumping plunger bores providing a pumping chamber at its inner end. The pump rotor has a coaxial throughbore providing a valve bore intersecting the annular arrangement of plunger bores. A poppet valve, axially shiftable in the valve bore, has a sealing head engageable with a valve seat at the inner end of the rotor throughbore. An armature of a valve electromagnet is fixed to the outer end of the poppet valve for attraction by a coaxial stator when the electromagnet is energized. The poppet valve and armature are coupled to the pump rotor for rotation therewith. A coaxial accumulator bore is provided in a drive shaft adjacent the inner end of the rotor throughbore for supplying fuel to and receiving spilled fuel from the pumping chamber.

Abstract: A rotary distributor fuel injection pump having a fuel system for circulating fuel continuously from a fuel supply pump via an end chamber at one end of the distributor rotor and an annular fuel chamber surrounding the distributor rotor to a return line and a pressure regulator in the return line for regulating the upstream pressure and continuously returning excess fuel to the supply pump. An electrical control valve is selectively opened during the pumping strokes to spill fuel into the end chamber and terminate the fuel injection event. An auxiliary passage in the rotor resets the pressure in the distributor outlets to approximately the same initial pressure. In an air purging mode of operation, the control valve is held closed until after the distributor port moves out of registry with each distributor outlet to prevent back flow to the end chamber.

Abstract: A fuel filter assembly employs a retainer collar for locking the disposable cartridge to the base. The base and the retainer collar are configured with a pair complementary spiral ramp-like structures. The retainer collar is rotatable so that the catches are positioned in slots of the base for locking the cartridge to the base. A spring washer biases the retainer collar into the locked position.

Abstract: A key system for a fuel filter assembly employs angularly spaced arcuate protrusions which protrude radially from the cylindrical sidewall of the cartridge. The base has corresponding tracks defined by equidistantly spaced rails which engage with the protrusions to key the cartridge with the base. The key system is employed either apart from or in conjunction with a second axial key/slot system of the base and the cartridge.

Abstract: An apparatus and a process for recycling used engine coolant employs a reverse osmosis process for separating ethylene glycol from a concentrate coolant solution. The engine coolant concentrate is pre-filtered through a series of filters and pressurized prior to being passed through a semi-permeable membrane. The membrane separates the feed stream into a permeate solution of ethylene glycol and water and concentrate solution. The concentrate solution is returned to a concentrate tank for continuous circulation through the apparatus. A heat exchanger maintains the temperature of the concentrate solution below a pre-established threshold.
