Patent number: 7748750Abstract: A fitting for collecting or distributing high-pressure fluid via fluid transmission lines is provided. The fitting includes a body, and a plurality of apertures formed in the body in a common plane, intersecting inside the body such that all of the apertures are in mutual fluid communication. The fitting also includes first and second compression members positioned on opposing sides of the body and coupled thereto so as to exert a compressing bias to the body in an axis perpendicular to the common plane. The compression members each comprise a raised contact surface corresponding to the region of the body where the plurality of apertures meet, and through which the compressing bias is exerted. The fitting may be an elbow-fitting, a tee fitting, a cross-fitting, or some other configuration.Type: GrantFiled: August 19, 2004Date of Patent: July 6, 2010Assignee: Flow International CorporationInventors: Chidambaram Raghavan, Mohamed A.

Patent number: 7726331Abstract: A modular fluid handling device includes at least one block having opposing block faces shaped as tessellating regular polygons, and a series of block sides therebetween. Each block includes a central bore and fluid passages extending between the block faces, and possibly ducts extending between the bore and the fluid passages. The blocks may be rapidly horizontally and/or vertically affixed with their bores and/or fluid passages in communication to form a fluid handling device having the desired configuration (e.g., with the bores and fluid passages forming a desired process flow path, fluid circuit, or the like). Star wheels and/or rotor discs can be provided within the block bores for purposes of pumping fluids flowing within the bores, and/or for purposes of deriving power from fluid flow within the bores.Type: GrantFiled: May 23, 2007Date of Patent: June 1, 2010Inventor: Gregory C. Giese

Publication number: 20100066077Abstract: A connection joint brazed to a heat exchanger may employ a first block and a second block. The first block may have two fluid passages that align with two fluid passages of the second block. A first male insert may reside within a first fluid passage of each of the first block and the second block and a second male insert may reside within a second fluid passage of each block. Each of the male inserts may employ a first seal and a second seal with a raised boss region midway between the seals. The raised boss portion lies at the mated flats of the juncture of the first and second blocks, which are chamfered to permit part of the boss to locate in each of the chamfers. The seals may be o-rings they may be molded onto an insert base using an over molding or double shot manufacturing process.Type: ApplicationFiled: September 15, 2008Publication date: March 18, 2010Applicant: DENSO International America, Inc.Inventor: Rajeev Sharma

Patent number: 7637538Abstract: A heater core assembly includes a heater core having two tube stubs projecting therefrom. Two heater tubes engage the two tube stubs, respectively, to define respective abutting interfaces therewith. A clamp couples the heater tubes to corresponding ones of the tube stubs. The clamp includes a first bracket half having two arcuately-shaped openings formed therein for accommodating the stub/tube pairs at the abutting interfaces to permit the stub/tube pairs to extend transversely to the clamp. A second bracket half is hinge connected to the first bracket half to permit opening and closing of the clamp. The second bracket half has two arcuately-shaped openings to accommodate the stub/tube pairs when the second bracket half is pivoted onto the first bracket half. A latch latches the first bracket half and the second bracket half to each other when the clamp is closed.Type: GrantFiled: April 27, 2007Date of Patent: December 29, 2009Assignee: Behr America, Inc.Inventors: Michael Tchang, Steven Dargel, David Forsyth

Patent number: 7547049Abstract: Embodiments of the invention provide new fittings and fitting assemblies for tight, leak-proof filter and fluid connections in a pump useful in dispensing fluid onto wafers during a semiconductor manufacturing process. One embodiment of a fitting assembly comprises an o-ring-less low profile fitting and a low profile male threaded locking nut. A manifold of the pump is machined with a female threaded hole for receiving the fitting and the locking nut. The fitting has higher compressibility than the manifold. Initially, as one end of the fitting touches the bottom of the receiving hole, there is a small gap between the end of the fitting and the bottom of the receiving hole. As the fitting is pressed down, the end of the fitting that touches the bottom of the receiving hole begins to deform and fill the small gap, thus creating a tight seal between the fitting and the manifold.Type: GrantFiled: November 20, 2006Date of Patent: June 16, 2009Assignee: Entegris, Inc.Inventor: Iraj Gashgaee
