  • Patent number: 7234706
    Abstract: A seal (301) has a first surface capable of contacting a valve cover (101) over a first fluid while a second surface, opposed to the first surface, is capable of contacting a seal seat (303). The seal (301) also has a third surface capable of contacting a sensor (201) disposed in a second fluid, while a fourth surface, opposed to the third surface, is capable of contacting the seal seat (303). The seal (301) is capable of separating the first fluid from the second fluid while preventing the first fluid and the second fluid from leaking out of the valve cover (101).

  • Patent number: 6942221
    Abstract: A sealed flange includes a seal (203 or 901) and a flange (201 or 801). The outer perimeter of a flange (201 or 801) has tabs (303 or 803) interspaced with notches (601 or 805). The outer perimeter of a seal (203 or 901) has spacers (305 or 903) interspersed with gaps (501 or 909). When the seal (203 or 901) is disposed along the outer perimeter of the flange (201 or 801), the tabs (303 or 803) fit in the gaps (501 or 909) of the seal (203 or 901) while the spacers (305 or 903) fit in the notches (601 or 805) of the flange (201 or 801). The outer perimeter of the sealed flange comprises the outermost edges of the tabs (303 or 803) of the flange (201 or 801) and the outmost edges of the spacers (305 or 903) of the seal (203 or 901).

  • Patent number: 6913267
    Abstract: A cylinder head gasket (211) includes one or more alignment holes (301) and one or more drain-back holes (303) disposed in an area of the cylinder head gasket (211). One or more push rods (211) are extendable through the alignment holes (301). The one or more drain-back holes (303) are formed such that the one or more push rods (211) are incapable of fitting through the one or more drain-back holes (303).

  • Patent number: 6752590
    Abstract: A water pump (10) and impeller (30) for use in applications such as internal combustion engines. A plurality of holes (40, 44) are formed near the hub and periphery of the impeller (30) of the water pump to provide coolant flow through a cavity (22) housing a seal. The seal (18) is thereby cooled to prevent premature failure of the seal (18) due to overheating.

  • Patent number: 6460512
    Abstract: A combustion gasket having dual material structures is provided. The combustion gasket has a rigid material structure adjacent to a resilient material structure. The rigid and resilient material structures independently engage the connected surfaces. In the case of a fuel injector mounted on a cylinder head of an internal combustion engine, the connected surfaces are an injector ledge formed by the fuel injector and a cylinder ledge formed by the cylinder head. The rigid material structure bears the load, for example of a fuel injector, and may partially seal the connection.

  • Patent number: 6374806
    Abstract: A fluid delivery system for delivering a supply of a fluid from a fluid source to a fuel injector includes a rail for conveying a fluid and being positionable proximate the fuel injector. The rail has a fluid passageway defined therein, the fluid passageway being in fluid communication with the source of fluid. A connector is in fluid communication with both the rail and with the fuel injector for fluidly connecting the rail to the fuel injector. The connector is universally moveable in three axes for accommodating static tolerances existing between the rail and the fuel injector and for accommodating dynamic relative motion between the rail and the fuel injector such that stresses imposed on the fuel injector resulting from being attached to the rail are substantially eliminated.

  • Patent number: 5660521
    Abstract: A water seal coolant wick comprises a ring of absorbent material, such as felt, disposed in the drain cavity between the inner radial face of a water pump seal in a water pump and the bearing housing so that the wick is disposed in the leakage path between the seal and the drain cavity weep hole, the wick preferably completely filling the drain cavity and acting to absorb insignificant weepage from the seal and keep it within the housing, out of sight, while allowing substantial leakage, which would be indicative of pump failure, to flow out of the weep hole.

  • Patent number: 5367993
    Abstract: A valve cover assembly for an internal combustion engine has an integrally formed spark plug tube extending therethrough and into a cylinder head. The blind joint between the spark plug tube and the cylinder head surface against which it abuts is provided with a unique joint seal assembly wherein a flange surface generally parallel to the cylinder head surface is provided on the outer periphery of the tube and the tube is reversely tapered from the flange to the end thereof. An elastomeric sealing ring is mounted on and retained in place by the reverse taper below the flange and abuts against the cylinder head. The ring is thus retained on the tube during installation and removal of the valve cover from the cylinder head while growth of the ring due to the hot oil environment is accommodated by the radial extent of the flange surface.

  • Patent number: 5035637
    Abstract: A plastic gasket assembly of substantially increased thickness, compared to present day elastomeric or composition gaskets, for use in sealing an engine valve cover to a cylinder head thereof, the gasket including a portion incorporating an electrical conductor for creating an electrical bridge through the sealing area between the cylinder head and valve cover by means of which exterior control circuitry can be electrically coupled to electrical or electronic devices disposed internally of the valve cover. In a first embodiment, the wires connecting the devices to the control unit are simply molded into the gasket whereas in a second embodiment, the gasket is drilled or molded to provide holes for inserting the wires, sealing of the wires being accomplished by clamping of the gasket and/or sealant disposed on the wire.
