Patent number: 6651574Abstract: A valve includes a housing with an elongated bore having a longitudinal axis and a spool reciprocatingly mounted within the bore for relative movement along the bore parallel to the axis. The housing has a housing passageway and the spool has a spool passageway. The passageways align in at least one axial position of the spool along the bore, whereby fluids can pass between the spool and the housing. The passageway of one of the spool or the housing includes a first groove which extends parallel to the axis, but not substantially about said one of the spool or the housing. The passageway of another of the spool or the housing includes a second groove which extends circumferentially about said another of the spool or the housing.Type: GrantFiled: January 11, 2002Date of Patent: November 25, 2003Assignee: Teleflex Canada Limited PartnershipInventors: Mark William Ellens, Jan Kuyper, Neal Wesley Denis Wood, Steven Michael Winiski, Randall Theodore Mark

Patent number: 6579072Abstract: A rotary pump has a rotor with a first end, a second end opposite the first end, a central bore and a plurality of cylinder bores arranged about the central bore and extending completely through the rotor from the first end to the second end. There is a plurality of pistons, each piston being reciprocatingly received in one of the bores. A swash plate member has a swash plate adjacent the second end of the rotor and a spigot extending through the central bore of the rotor. There is in an end cap connected to the first end of the rotor. The end cap closes off the bores at the first end of the rotor. A drive shaft is rigidly connected to the end cap and extends away from the rotor. There is a cover having an aperture rotatably receiving the drive shaft. The cover extends about the end cap and the rotor and is connected to the swash plate member.Type: GrantFiled: July 27, 2001Date of Patent: June 17, 2003Assignee: Teleflex Canada Limited PartnershipInventors: Dana Trousil, Jan Kuyper
