Patent number: 7703475Abstract: A piston for a linear spool valve, the valve comprising a body having a inner surface. The body is made of a material with a relatively low heat expansion coefficient ?1. The piston comprises a contact member having an outer surface and being adapted to reciprocate within the body of the valve so that the outer surface is in contact with the inner surface. The contact member has at least a first layer made of a material with a heat expansion coefficient ?2 essentially greater than ?1, i.e. ?2>>?1, and at least a second layer made of a material with a heat expansion coefficient ?3 close to ?1. This causes the contact member to be adapted to behave, along said outer surface, as a material having a heat expansion coefficient essentially closer to ?1 than to ?2. One of the layers constitutes an outer layer of the contact member and comprises the outer surface.Type: GrantFiled: June 6, 2006Date of Patent: April 27, 2010Assignee: I.D.E. Technologies Ltd.Inventors: Henrikh Rojanskiy, Avraham Ophir

Patent number: 7694937Abstract: A valve assembly configured to be mounted on a support structure comprises a flowbody having a first port, a second port, and a flow passage there between. A flange is coupled around the flowbody proximate the first port. A sleeve extends into the flowbody through the first port, and a radial lip is coupled to the sleeve proximate the first port. A retaining ring is coupled to the flange and configured to confine the radial lip between the retaining ring and the support structure to secure the sleeve within the flowbody when the valve assembly is mounted on the support structure.Type: GrantFiled: August 9, 2006Date of Patent: April 13, 2010Assignee: Honeywell International Inc.Inventors: David E. Stout, Tom J. Phielix, Christopher L. Thomas

Patent number: 7686032Abstract: In a scuba diving first stage pressure regulator soft silicone rubber is bonded to the first stage spring to prevent water from freezing between the coils of the spring thereby assuring unrestricted movement of the spring coils even during freezing conditions. By placing a soft molded material bonded directly to the spring surface through the method of chemical and/or mechanical bonding, a soft pliable silicone rubber encapsulates or cocoons the entire area between spring coils and works as a barrier to prevent water from filling the regions between the spring coils and freezing in cold diving conditions. The thickness and volume of the pliable material silicone is not critical as long as the area between the coils is occupied with enough material to prevent ice from forming and otherwise preventing the spring from deflecting. Further, a radial clearance hole is needed to allow the piston to fit inside the silicone bonded spring hollowed center.Type: GrantFiled: November 6, 2006Date of Patent: March 30, 2010Inventor: Dean R. Garraffa

Patent number: 7628687Abstract: A cover assembly for an aperture in a wall may include: a first support and a second support provided on the wall, each support including a monolithic receptacle; a first pin-portion and a second pin-portion rotatably mounted in the receptacles, respectively, to define respective pivot-hinge arrangements; and a cover coupled to the first and second pin-portions. For example, the wall may be a part of fluid (e.g., air) duct disposed in a vehicle, and the cover may be oriented with respect to the wall so that the aperture represents one of an inlet and an outlet.Type: GrantFiled: November 3, 2004Date of Patent: December 8, 2009Assignee: DENSO CorporationInventors: Kiyotaka Nitta, Akio Hirano, Naohisa Nishimura

Patent number: 7621292Abstract: A modular lining system for a valve body for use in fluid handling systems including fluid transport tankers, and a method for lining a valve body using the modular lining system. The lining system is slidably inserted into the valve body to protect the valve body from corrosive or other damaging materials. The liners are placed such that they are easily removable for cleaning or replacing when damaged. An actuator comprising a piston is actuated within one of the liners to selectively allow and stop fluid flow.Type: GrantFiled: April 10, 2007Date of Patent: November 24, 2009Assignee: Betts Industries, Inc.Inventor: Kenneth Eernisse

Patent number: 7571742Abstract: An outflow valve is disclosed for use in a pressure vessel. The outflow valve includes a dual wall valve housing having a central bore, a butterfly plate assembly and an angled drive shaft. The butterfly plate assembly is designed to fit and rotate within the central bore. The angled drive shaft has first and second ends rotateably coupled to the dual wall valve housing, and the angled drive shaft is attached to the butterfly plate. The drive shaft is designed to rotate the butterfly plate assembly between a closed position and an open position within the central bore.Type: GrantFiled: March 23, 2005Date of Patent: August 11, 2009Assignee: Honeywell International Inc.Inventors: Darrell W. Horner, Simon L. Waddell, Christopher L. Thomas, Steven D. Carter

Patent number: RE42632Abstract: A recessed, frostproof water faucet having a tubular stem connected to a pivot plumbing unit connected to a subsurface water line through the rear wall of a box-like recess unit. A slider connector connects the water faucet tubular stem and the access panel or lid of the recess unit. The lid pivots on hinges and as one lifts the lid, the faucet is lifted by the slider connector from a horizontal storage position to a vertical locked position for use, the slider connector being connected to a faucet flange and sliding along grooves in tracks mounted along the inner side of the lid. A sliding hinge locks the lid upright, sliding downward along the upper end of the rear wall. The faucet is returned to the storage position by pulling upward and lowering to the closed position, the slider connector sliding forward along the grooves to the stored position.Type: GrantFiled: August 25, 2005Date of Patent: August 23, 2011Assignee: M & H Waterworks, L.L.C.Inventor: Danny Heflin
