Patent number: 6585491Abstract: A liquid discharge head is provided having a heating member for generating thermal energy to create a bubble in liquid, a discharge port adapted to discharge the liquid, and a liquid flow path communicated with the discharge port having a bubble generating area for enabling the liquid to create the bubble. A movable member is arranged in the bubble generating area to be displaced along with the development of the bubble. A regulating portion regulates the displacement of the movable member within a desired range, and by means of energy at the time of bubble creation, the liquid being discharged from the discharge port. The regulating portion is arranged to face the bubble generating area in the liquid flow path. A support member is directly connected to the movable member. The bubble development causes the movable member and the regulating portion to be in contact forming an essentially closed space with the exception of the discharge port.Type: GrantFiled: October 30, 2001Date of Patent: July 1, 2003Assignee: Canon Kabushiki KaishaInventors: Yoichi Taneya, Sadayuki Sugama, Hiroyuki Ishinaga, Hiroyuki Sugiyama, Satoshi Shimazu

Patent number: 6585492Abstract: A pumping system is disclosed that includes a vacuum source. The pumping system includes a motor coupled to a centrifugal pump and a separator defining a reservoir in fluid communication with an inlet of the centrifugal pump. A water liquid ring vacuum pump having an inlet is provided in fluid communication with the reservoir of the separator. Accordingly, the vacuum pump may provide the required vacuum to prime the pump. To backflush that pumping system, the pumping system may include a first valve provided between the discharge port of the vacuum pump and the reservoir of the separator. A second valve may be provided between the reservoir of the separator and the inlet of the water liquid ring vacuum pump. During normal operation, the first valve fluidly connects the discharge of the vacuum pump to the atmosphere and the second valve fluidly connects the inlet of the vacuum pump to the reservoir of the separator.Type: GrantFiled: July 17, 2001Date of Patent: July 1, 2003Inventors: David Muhs, Gianfranco Parma

Patent number: 6585493Abstract: A hygienic, self-priming centrifugal pump (1) with a pump housing (4) provided with an inlet opening (2) and a pressure connecting piece (3), where an impeller wheel (7) can rotate inside said pump housing. The inlet opening (2) is connected with a liquid ring pump section (9) comprising an auxiliary housing (10) and a pump screw (11). The pump screw (11) is mounted on and in extension of the hub (7a) of the impeller wheel. A recycling pipe (15) for pump liquid connects the pressure connecting piece (3) of the centrifugal pump and the auxiliary housing (10) of the liquid ring pump section (9), optionally the inlet nozzle (16) or the inlet pipe (18) of the latter. All the surfaces in the pump housing (4) and the auxiliary housing (10) in direct contact with liquid should be smooth and rounded and without holes, crevices, beads or burrs.Type: GrantFiled: September 20, 2001Date of Patent: July 1, 2003Assignee: APV Fluid Handling Horsens A/SInventor: Michael Sutton

Patent number: 6585494Abstract: Variable-capacity control is reliably carried out without using a large pressure control valve while maintaining sufficient pressure resistance in a refrigerating cycle in which carbon dioxide is used as its coolant. A pressure sensor for measuring the pressure on the low pressure side of this refrigerating cycle is used. The electromagnetic coil of the pressure control valve is controlled so that the measured pressure approaches the target value. Low pressure is applied equally to both ends in the direction of movement of the valve disc of the pressure control valve, so that the valve disc can be moved by a light load, and hence the size of the electromagnetic coil can be small.Type: GrantFiled: December 4, 2001Date of Patent: July 1, 2003Assignee: Zexel Valeo Climate Control CorporationInventor: Nobuhiko Suzuki

Patent number: 6585495Abstract: A fluid pump is provided that produces an outflow of fluid that is not proportional to the speed of the input drive. Thus, the fluid pump can be tuned to provide a substantially constant outflow of fluid irrespective of the speed of the input drive. The fluid pump also provides fluid outflow when the rotational direction of the input drive is reversed.Type: GrantFiled: June 11, 2002Date of Patent: July 1, 2003Assignee: International Truck Intellectual Property Company, LLCInventor: James A.

Patent number: 6585496Abstract: A scroll compressor is provided with an oil reservoir that is self-regulating dependent on the overall lubricant level in the compressor. The reservoir is provided by a structural member having an inner rim and a bottom wall. The bottom wall is provided with a metering orifice that returns lubricant to the main sump. The metering orifice will ensure that undue amounts of lubricant are not maintained in the reservoir during low oil operation.Type: GrantFiled: January 24, 2002Date of Patent: July 1, 2003Assignee: Scroll TechnologiesInventor: Zili Sun

Patent number: 6585498Abstract: A motor-pump unit including an electric motor and a pump. The pump is concentrically surrounded by the rotor/stator of the motor. The rotor of the electric motor is U-shaped, viewed in an axial section. The cross-piece of the “U”, in the region of the common axis, is provided with an interior toothing. The shaft of the pump includes a pinion that meshes with the interior toothing of the cross-piece of the “U”.Type: GrantFiled: May 8, 2002Date of Patent: July 1, 2003Assignee: Voith Turbo GmbH & Co KGInventors: Franz Arbogast, Gerd Hundt, Thomas Neubert
