Patent number: 7318539Abstract: A battery operated, handheld fluid dispenser comprises a supply container having a body portion and a narrow neck extending upwardly therefrom. A pump and discharge unit is mounted on the upper end of the neck and comprises a pump diaphragm and pump chamber for pumping liquid from the container to a discharge nozzle. A battery powered pump drive unit is mounted on the container and comprises an electric motor having an output shaft coupled with the pump diaphragm through a cam and cam follower arrangement to displace the diaphragm through a pump stroke when the motor is energized. The cam is rotatably driven by the motor, and the cam follower is attached to the diaphragm, whereby rotation of said cam axially displaces the diaphragm, and the cam and cam follower have interengaging dual cam faces for balancing lateral forces therebetween during rotation of said cam relative to said cam follower.Type: GrantFiled: April 13, 2004Date of Patent: January 15, 2008Assignee: Power Sprayer LLCInventors: Marc L. Vitantonio, Craig M. Saunders, Donald C. Fuchs, Jr., Daniel J. Wanhainen

Patent number: 7314031Abstract: A camshaft assembly 16 is disclosed for an engine 10, along with a method of producing the camshaft 16. The camshaft includes a support shaft 22 that carries in the region of one end 26 a camshaft element. The camshaft element may comprise a rotation sensor target member 24 and the support shaft 22 is preferably a tubular shaft. The camshaft element 24 is captured onto the support shaft 22 by deforming a deformation zone 46 at the end of the support shaft 22 into a radially extending rivet head 28.Type: GrantFiled: April 2, 2004Date of Patent: January 1, 2008Assignee: Renault s.a.s.Inventors: Christophe Le Troadec, Yves Gourlay

Patent number: 7284521Abstract: A camshaft of an automotive engine includes two concentric contra-rotating shafts mounted one inside the other, namely an inside shaft and an outside shaft, at least one cam rotatably mounted on the outside shaft, fixedly connected to the inside shaft radially through the outside shaft via a fastening mechanism, a sleeve gripped by the fastening mechanism and inserted fixedly into aligned boreholes in the inside shaft and in the cam, a core that widens the material of the sleeve within its elasticity limits in the area of the inside shaft and is inserted into the sleeve after insertion of the sleeve into the shaft mechanism. To improve mountability, the core extends over the entire length of the sleeve and widens it beyond the area limited by the inside shaft without exceeding the upper limit of elasticity of the material of the sleeve in comparison with its uninstalled starting state.Type: GrantFiled: January 18, 2006Date of Patent: October 23, 2007Assignee: MAHLE International GmbHInventors: Martin Lechner, Falk Schneider

Publication number: 20070221011Abstract: Disclosed is a laborsaving cam wheel structure formed of a fixed member and a movable member each having two slopes spirally running in reversed directions on the respective inner side. The slopes of the fixed member are respectively abutted against the slopes of the movable member such that when the movable member is biased relative to the movable member, the peak ends of the slopes of the movable member are moved along the slopes of the fixed member toward the root ends of the slopes of the fixed member.Type: ApplicationFiled: October 10, 2006Publication date: September 27, 2007Inventors: Chih-Yuen Wang, Chia-Cheng Chen

Patent number: 7243575Abstract: An indexing and braking mechanism for a manual transmission having a shifting mechanism and at least one rotatable drive shaft is disclosed. The mechanism includes an indexing mechanism for controlling movement of the shifting mechanism between at least a first position and a neutral position. The indexing mechanism has a plate having a plurality of notches formed thereon, wherein one notch corresponds to the first position and another notch corresponds to the neutral position. A locking mechanism is provided for selectively limiting movement of one of the at least one rotatable drive shaft. The locking mechanism is adapted to selectively engage the plurality of notches to selectively maintain the indexing mechanism in one of the first position and the neutral position. The locking mechanism includes an indexing lever having a contact surface for contacting the rotatable drive shaft.Type: GrantFiled: March 25, 2003Date of Patent: July 17, 2007Assignee: BRP-Rotax GmbH & Co. KGInventor: Gerhard Niederwimmer

Patent number: 7240582Abstract: An override device is proposed to permit the manual operation of a closure which is normally driven by an electric motor. The override device comprises a manual closure driving mechanism, such as a chain engaged around a pulley, which when operated first produces the translation of a first gear along its rotation axis until this first gear meshes with a second gear connected to the output shaft of the motor which normally drives the closure. During the translation of the first gear, a switch is tripped to safely interrupt power to the motor and a mechanism is operated to disengage the motor from the output shaft. Thereafter, further operation of the chain, and therefore further rotation of the pulley, is adapted to cause the first gear to rotate instead of translating, whereby the second gear is driven into rotation by the first gear thereby causing the rotation of the output shaft and the manual operation of the closure.Type: GrantFiled: July 8, 1994Date of Patent: July 10, 2007Inventors: Michel Manaras, Eddy Desrochers

Patent number: 7234428Abstract: An internal combustion engine including an engine housing having a cam chamber and an aperture providing access to the cam chamber. The engine also includes an insert at least partially made from plastic received within the aperture, a crankshaft coupled to the engine housing for rotation about a crank axis, and a cam shaft defining a cam shaft axis and at least partially made from plastic that is rotatably driven by the crankshaft. The cam shaft includes first and second ends and at least one cam lobe positioned between the ends. The first end is rotatably supported by the engine housing and the second end is rotatably supported by the insert. The engine also includes a metal portion coupled to either the insert or the cam shaft. The metal portion defines a flange having a face in contact with an adjacent surface of the other of the insert and the cam shaft.Type: GrantFiled: July 28, 2005Date of Patent: June 26, 2007Assignee: Briggs and Stratton CorporationInventors: John J. Nagel, John A. Zbiegien, Jr.
