Patent number: 7331316Abstract: If it is determined that an engine has been started, an engine coolant temperature is detected. If the engine coolant temperature is equal to or lower than a threshold value, the catalyst quick warm-up control is started to retard ignition timing, and a signal indicating a command to increase an operate angle is transmitted to a VVLA controller. When a VVT hydraulic pressure is increased to a predetermined value, a signal indicating a command to decrease the operate angle is transmitted to the VVLA controller, and a signal indicating a command to advance open timing of an intake valve is transmitted to a VVT controller so that the open timing of the intake valve is not changed. If the engine coolant temperature is equal to or higher than a threshold value, the catalyst quick warm-up control ends, and the ignition timing is returned to normal timing.Type: GrantFiled: October 3, 2006Date of Patent: February 19, 2008Assignees: Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Kiyoo Hirose, Kazuto Ikeda, Hiroshi Morita

Patent number: 7331317Abstract: A valve timing control system for an internal combustion engine, which is capable of accurately and delicately controlling an amount of intake air, and thereby maintaining excellent combustion state and reduced exhaust emissions. The valve timing control system variably controls the valve-closing timing of an intake valve with respect to valve-opening timing of the same as desired via a variable intake valve actuation assembly. The ECU of the engine determined a basic value of a target auxiliary intake cam phase according to the demanded drive torque of the engine. The ECU calculates a control input to the variable intake valve actuation assembly such that the cylinder intake air amount converges to a target intake air amount and at the same time the auxiliary intake cam phase is constrained to the basic value of the target auxiliary intake cam phase.Type: GrantFiled: May 28, 2004Date of Patent: February 19, 2008Assignee: Honda Motor Co., Ltd.Inventors: Yuji Yasui, Akiyuki Yonekawa

Patent number: 7331329Abstract: Reducing leakage within fuel injectors is one way in which the efficiency of the overall fuel injection system can be improved. In most fuel injectors that include a direct control needle valve, the needle valve member is still biased toward a closed position by a spring that is located in a spring chamber connected to a low pressure vent. In many instances, the needle valve member is guided in a tight clearance region adjacent the spring chamber. Since the internal plumbing of the fuel injector is connected to a high pressure rail during and between injection events, static leakage across the guide region of the needle valve member can reduce efficiency. Static leakage is reduced in the present invention by connecting the spring chamber to the common rail instead of to a low pressure vent.Type: GrantFiled: July 15, 2002Date of Patent: February 19, 2008Assignee: Caterpillar Inc.Inventors: Steven Y. Tian, Scott F. Shafer, Daniel R. Ibrahim, Ronald D. Shinogle, Amy M. Hess

Patent number: 7331360Abstract: The present invention relates to the field of check valves and more specifically to check valves with substantially low operational noise or low shut off noise. Provided is changing a direction of a fluid that closes a first and second flap to produce a slit, gap or orifice. Also provided is passing the fluid through the slit that reduces the speed of the fluid. The reduced speed fluid slowly closes a third flap and reduces shut off noise. The closed third flap creates a tight seal to stop any further fluid flow.Type: GrantFiled: January 28, 2005Date of Patent: February 19, 2008Inventor: Theodore Gerald Camis, Jr.

Patent number: 7331361Abstract: To protect hydraulic assemblies, in particular to protect hydraulic brace systems, pressure relief valves 1 are used, the closing part 10 of which is formed by a piston 15, which is connected to the connection 4, and the valve spring retainer 12, which comprises said piston, is arranged displaceably thereon and accordingly has a cylindrical design. Between the connection 4, which is equipped with a blind hole 5 and radial bores 6, 7, and the displaceable closing part 10 and/or the correspondingly shaped valve spring retainer 12 a damping chamber 20 is formed, which is directly connected to the blind hole 5 and hence to the system pressure.Type: GrantFiled: January 31, 2005Date of Patent: February 19, 2008Inventor: Wolfgang Voss

Patent number: 7331362Abstract: A valve includes a hollow pipe defining a first opening and a second opening aligning with each other. A first passage, a second passage, a third passage and a fourth passage are respectively defined in an inner surface of the hollow pipe and communicate with each other. A piston is received in the hollow pipe and forms a first flange and a second flange thereon. A first stop is formed above the first flange and has long sides and short sides. A second stop is formed below the second flange and has long sides and short sides. The first flange and the second flange blocking the third passage and the fourth passage depends on the short sides/long sides being aligned with the third passage and the fourth passage, whereby water discharge path is controlled easily and exactly.Type: GrantFiled: June 29, 2005Date of Patent: February 19, 2008Assignee: Globe Union Industrial Corp.Inventor: Ouyang Huei

Patent number: 7331363Abstract: Procedure consisting of the of textile weaving of inelastic and elastic fiber forming an elastic weave with one or more rigid loops. Field of application: clothing, footwear, headgear, haberdashery, costume jewelry, items for personal use, travel items, cases, leather goods and imitation leather goods. The inventive procedure consists of the weaving of an inelastic fiber and an elastic fiber, natural or synthetic, which are separated at preset intervals, in this way giving rise to one or more rigid loops that allow the application of laces or other objects that benefit from the combined effect of resistance and/or stability, provided by the loop in inelastic fiber, and of elasticity, provided by the inelastic-elastic weave.Type: GrantFiled: June 14, 2004Date of Patent: February 19, 2008Assignee: Lanzi S.R.L.Inventor: Enzo Lanzi

Patent number: 7331364Abstract: A gas mask filter canister of varying shapes is filled by orienting the a fill opening to face upwardly, introducing into the fill opening a particulate filter material, and vibrating the filter canister at a frequency and amplitude, and for a time until a predetermined packing density is reached. The invention can be used to fill elliptical or other odd shaped filter canisters having a concave profiles to conform closely to the curvature of the wearer's face.Type: GrantFiled: April 24, 2003Date of Patent: February 19, 2008Assignee: Avon Protection Systems, Inc.Inventor: John Schlacchter

Patent number: 7331365Abstract: A shut off valve (10) is provided for use in an aircraft lavatory system (70) during maintenance sanitizing operations. The shut off valve includes an inlet passage (20) in intermittent fluid communication with an outlet passage (30) and a magnetic flapper body (40) movable between a rest position and a seal position between said inlet passage and said outlet passage. The flapper body is moved by a magnetic actuator (60) whereby upon placing said magnetic actuator within the proximity of the flapper body, the flapper body is moved form the rest position and, with the assistance of fluid flow within the valve, into the seal position, thus preventing fluid communication between the inlet passage and the outlet passage.Type: GrantFiled: February 28, 2003Date of Patent: February 19, 2008Assignee: Transdigm Inc.Inventor: Hung Nguyen
