  • Patent number: 8910610
    Abstract: The present invention is an oil pump used in combination with a twin cam type engine, such as a HARLEY DAVIDSON® type A or type B engine, that includes a first high pressure gerotor and cam chest scavenger gerotor housing, a separator plate that establishes an independent dual scavenging capability and a second crankcase sump scavenger gerotor housing that pulls oil from the crankcase sump. The oil pump also includes a high pressure gerotor that pulls oil from an oil reservoir and supplies oil under pressure through a stock or aftermarket cam plate to the engine, a cam chest scavenger gerotor to scavenge oil in a cam chest of the engine and return the oil to the oil reservoir, a crankcase sump scavenger gerotor to scavenge the oil in a crankcase sump of the engine and return the oil to the oil reservoir and an o-ring to prevent the oil from leaking into the cam chest of the engine.

  • Patent number: 5613869
    Abstract: Disclosed is a modular connector for a communication line. The inventive connector includes a body having a terminal side for inserting into a corresponding jack and a cable side for fastening to an end of the communication line. The connector also includes a spring-biased tab which has a first end connected to the terminal side of the body and a second free end. The tab has a pair of oppositely extending locking shoulders spaced from the free end of the resilient tab. The tab is movable for operatively engaging and disengaging the locking shoulders with corresponding internal abutting surfaces within the jack to secure and release the connector from the jack. A guard extends from the cable side of the body towards the terminal side of the body. At least a portion of the second free end of the tab is covered by a section of the guard for preventing the tab from catching another communication line or other object when its associated line is removed from the jack.
