A system for performing rapid charging and evacuation of systems that contain a fluid, such as cooling systems on refrigeration products. In addition, the invention relates to methods of accomplishing rapid charging and evacuation, as well as to tools that form part of the system and that are used to accomplish the methods.

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.

A service valve assembly that is designed to minimize leakage by reducing the number of leakage paths from the valve assembly. In addition, the service valve assembly is designed to permit connection to many different refrigeration systems and has higher flow capacity. The valve assembly is engageable by current servicing tools so that purchase of new service tools is not required. In the valve assembly, the service connection is designed as part of the shut-off valve and communicates with the condenser side port. Therefore, initial processing through the condenser side port and subsequent processing through the evaporation side port occur through the combined service connection and shut-off valve structure. Once installed, the described valve assembly has one leak path versus two leak paths in known valve assemblies.

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.

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.

A connection apparatus for connection with an inside of a fluid conduit including seal member, sleeve member and collet assembly to seal and grip the fluid conduit which is in fluid communication with a fluid passageway. The connection apparatus further includes a resilient member and a control valve to cause actuating and deactuating relative movement between the collet assembly and the sleeve member so as to grip and seal the inside of the fluid conduit.

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. When the positioning and retaining mechanism actuates the body member to the second position, the valves are opened, thereby permitting flow through the connector.

A pressure balanced coupling device for quick connection and disconnection with at least one mechanism. The device operates to maintain a sealed flow-through connection between two devices which may also contain a pressurized medium such as refrigerants. The preferred device permits non-destructive gripping of tubing while affording readily selectable means for safely releasing pressure from within the device prior to releasing the gripping connection provided by this coupling device.
