Publication number: 20020066487Abstract: Valves, particularly service connection valves for use with a refrigeration system and the like, to permit charging, evacuation and/or testing of the system, are disclosed. In one embodiment, the valve includes a valve seat, a valve body detachably connected to the valve seat, and a valve core detachably secured within the valve body. The valve body and valve core are removable together as a single unit from the valve seat. In another embodiment, the valve includes a valve seat, a valve body detachably connected to the valve seat, and a cap that are designed so that the action of unscrewing the cap from the valve body will never cause the valve body to be unscrewed from the valve seat. Therefore, unscrewing the cap from the valve body will never loosen the connection between the valve body and the valve seat, thereby preventing leakage between the valve body and valve seat.Type: ApplicationFiled: October 11, 2001Publication date: June 6, 2002Applicant: FASTEST, INC.Inventors: Robert B.

Patent number: 6050295Abstract: A valved fitting is provided which includes a body having a first end and a second end spaced from the first end, with a fluid passage extending through the body between the first and second ends. A valve seat is defined on the body within the fluid passage, and a valve assembly is removably disposed within the fluid passage for controlling flow through the fluid passage. The valve assembly includes a valve head that is engageable with the valve seat in sealable relation therewith. A higher flow area, and thus a higher flow rate, are achieved with the fitting of the invention as compared to conventional fittings which utilize a single-piece body with a Schrader valve, because the valve seat is defined on the body, and the valve head is engageable with the valve seat. Further, the valve assembly is removable, thereby allowing the valve assembly to be replaced when needed. The valved fitting of the invention is particularly useful on a service valve block for an air conditioning system.Type: GrantFiled: June 4, 1998Date of Patent: April 18, 2000Assignee: FasTest, Inc.Inventors: Stanlee W. Meisinger, Mark D. Medved

Patent number: 6039303Abstract: A quick connect connector for connecting to a fluidline in a safe, reliable manner. The connector includes a body member having a central fluid passageway with a valve fixedly secured therein for selectively controlling fluid flow through the passageway. A piston member is slideably engaged with the body member, with the body member being slideable relative to the piston member between a first position and a second position. A collet assembly or a ball detent assembly is connected to the piston member for connecting the fluidline, which has a valve at the end thereof, to the piston member. A positioning and retaining mechanism is provided for selectively controlling movement of the body member relative to said piston member between the first position and the second position and for retaining the body member at the second position. The collet assembly or the ball detent assembly initially secures the fluidline to the piston member prior to the valves in the fluidline and the body member being opened.Type: GrantFiled: November 25, 1997Date of Patent: March 21, 2000Assignee: FasTest, Inc.Inventors: Robert B.

Patent number: 5950679Abstract: The present invention provides a high pressure plug coupling for providing a quick, fluid tight connection to a fluid port having internal threads. The high pressure plug coupling includes a generally hollow, exterior sleeve, with a hollow cylindrical piston slideably disposed within the exterior sleeve. A split collet assembly is connected to an end of the piston and is moveable therewith relative to the exterior sleeve. The split collet assembly includes a distal end portion that is radially expandable and contractable, with an interior surface of the distal end portion being tapered. An expansion pin is moveably disposed within the collet assembly and the piston for expanding the distal end portion. The expansion pin includes a frustum-shaped end portion adjacent to the distal end portion, with the frustum-shaped end portion being engaged with the tapered interior surface when the distal end portion is radially expanded.Type: GrantFiled: February 10, 1998Date of Patent: September 14, 1999Assignee: Fastest, Inc.Inventors: Robert B.

Patent number: 5788290Abstract: A connector for providing a fluid tight connection to a fluid port having internal threads. The connector includes an exterior sleeve having a split collet retractably mounted therein. The split collet defines an axial bore and includes a distal end portion extending axially outward from an end of the sleeve and adapted for lockingly engaging the threads of the fluid port. A sealing structure is mounted on the distal portion of the collet for providing a fluid tight seal with an end portion of the fluid port. The connector further includes an expansion pin mounted within the axial bore of the split collet adjacent to the distal end portion of the split collet. The expansion pin cooperates with the split collet to move the split collet radially inward and outward. A cross member connects the expansion pin to the exterior sleeve for preventing relative axial movement between the exterior sleeve and the expansion pin.Type: GrantFiled: December 27, 1995Date of Patent: August 4, 1998Assignee: FasTest, Inc.Inventor: Stanlee W.

Patent number: 5507537Abstract: A fluid connector (40) for gripping and sealing on an external surface of a fluid conductor (61). The fluid connector (40) includes a seal (62) which is forced into a bore (70) of a piston (66) having a smaller diameter than the seal, so that the seal (62) is radially squeezed to seal the external surface of the fluid conductor (61). A collet assembly (50) of the fluid connector (61) is forced to reduce the diameter to grip the external surface of the fluid conductor (61). A spring (68) which is disposed in the piston (66) compensates seal preload mechanism for variations in fluid conductor size.Type: GrantFiled: June 2, 1994Date of Patent: April 16, 1996Assignee: FasTest, Inc.Inventors: Stanlee W.

Patent number: 4240466Abstract: A push-pull type fluid coupling having interfitting male and female bodies. The female body carries radially movable ball detents to lock the male body in position, the detents being held inwardly by a rigidly mounted sleeve which supports the female body for relative axial movement. Both bodies have spring biased fluid retaining valves which are opened when the bodies interfit but close when they are disconnected. Two axially disposed springs surround the female body member and coact with the sleeve to resist movement of the body members in one direction, thus providing one level of required uncoupling force while only one of the springs is operative to resist movement of the body members in the other direction, thus providing a reduced force requirement for coupling.Type: GrantFiled: January 15, 1979Date of Patent: December 23, 1980Assignee: Parker-Hannifin CorporationInventors: Eugene H. Herzan, Stanlee W. Meisinger
