Patent number: 8083936Abstract: The production of purified water from a residential reverse osmosis drinking water system is limited by the pressure build up in the holding tank or reservoir. While the pressure in the tank increases the brine or waste water continues to flow at a constant rate. This condition makes an undesirable out of proportion relationship between the purified water and the waste water. The production of product water is controlled by the differential pressure across the purification membrane, as the tank pressure increases the differential pressure decreases and reduced production of product water results. The purpose of the device is to utilize the increasing tank pressure as a force to actuate the valve that proportions the waste water in a direct relationship with the product water. The ratio between the product water and the waste water remains constant during the period that purified water is being delivered to the holding tank.Type: GrantFiled: March 3, 2009Date of Patent: December 27, 2011Inventor: Robert Walker

Patent number: 8052116Abstract: A fluid power system includes a hydraulic machine. A pilot-controlled supply valve controls high-pressure fluid to the machine. The valve is coupled between the hydraulic machine and a high-pressure fluid source, and includes a control port for an actuation signal. The supply valve allows passage of fluid from the machine to the fluid source, but blocks passage of fluid from the fluid source to the machine while closed, or permits passage of fluid from the fluid source to the machine while open. The supply valve biases toward closed or open according to an actuation signal at the control port. A pressurization valve is also coupled between the hydraulic machine and the high-pressure fluid source. The pressurization valve blocks passage of fluid from the fluid source to the machine while in a first position, and allows a restricted passage of fluid between its input and output ports while in a second position, to allow pressure to equalize on either side of the supply valve before the supply valve opens.Type: GrantFiled: September 29, 2006Date of Patent: November 8, 2011Assignee: The United States of America as represented by the Administrator of the U.S. Environmental Protection AgencyInventor: Charles L.

Patent number: 8011639Abstract: A valve of the invention includes a valve body having an inlet, an outlet, and a flow passage connecting the inlet and outlet, the inlet, the outlet and the flow passage being in general axial alignment within the valve body. A valve seat surrounds the flow passage and a valve closure member is movable towards and away from the valve seat to close and open the valve respectively. The valve closure member is a poppet-type closure member axially mounted to a stem. The stem has a plurality of pistons spaced apart along the length thereof, and the valve body has a plurality of cylinders fixed relative thereto, the pistons each being slidable in a respective cylinder. The valve closure member is movable by varying the pressure in the cylinders. Preferably each of the cylinders has an outlet port through a wall thereof which is exposed when the closure member has moved towards or into a fully open position, pressure within said cylinders dissipating through those outlet ports when the outlet ports are exposed.Type: GrantFiled: July 20, 2004Date of Patent: September 6, 2011Assignee: Goyen Controls Co.

Patent number: 7836694Abstract: A cooling air flow regulating device for controlling the flow of cooling air to an air bearing may comprise a housing with a piston and a spring disposed within. When the pressure of the cooling air is high, the piston is forced out of the path of the cooling air and into an open position. As the pressure of the cooling air decreases, the spring forces the piston back into the path of the cooling air, effectively blocking the flow of cooling air to the air bearing. The cooling air flow regulating device of the present invention may be useful for controlling the cooling of air bearings in turbochargers of turbocharged engine, where at low engine speed, cooling air is not required for air bearings. Methods for using the cooling air flow regulating device of the present invention are also provided.Type: GrantFiled: July 13, 2007Date of Patent: November 23, 2010Assignee: Honeywell International Inc.Inventor: Steven Don Arnold

Patent number: 7836915Abstract: A valve gate piston assembly, in an injection molding system, is positioned in a staggered arrangement such that one piston assembly overlaps that of another valve gate piston assembly thereby minimizing an overall centerline pitch between said piston assemblies. Such a superposed layout of piston assemblies enables larger diameter pistons to occupy a smaller footprint than would be realized should the same piston assemblies be positioned side by side. The use of relatively larger diameter pistons results in an increased force available, for the same input air pressure, to actuate the pistons and valve stems attached thereto, resulting in a higher valve stem closing force. A staggered piston assembly layout also allows independent air circuits to control each piston separately. A combination of multiple piston assemblies may be configured in such a staggered, overlapping array.Type: GrantFiled: September 24, 2007Date of Patent: November 23, 2010Assignee: Husky Injection Molding Systems Ltd.Inventors: Patrice Fabien Gaillard, Manon Danielle Belzile, Edward Joseph Jenko
