  • Patent number: 6814098
    Abstract: A support structure for a C-ring includes a pair of circumferentially spaced holding members on catch plates. The holding members may be moved individually into the C-ring after the C-ring is mounted within an outer housing. The two holding members thus provide support to an inner periphery of the C-ring. A locking plate has support structure moved between circumferential ends of the housing members, thus providing effective support for the C-ring around its entire inner periphery. In this way, the two parts secured by the C-ring need not be moved relative to each other to insert the C-ring. The clearance or ability to move one of the two parts relative to the other which has been required in the past to mount a C-ring, is not necessary. This makes the inventive C-ring particularly useful for new applications, such as holding a porting sleeve within a valve housing.

  • Patent number: 6695000
    Abstract: A valve with an integral means for bleeding internal pressure prior to separation of a bonnet for the valve from its engagement with the valve body, provided by a bore through the valve body. This allows the internal pressure of the valve to equalize with atmospheric pressure prior to complete disassembly of the bonnet from the valve body. The bore through the valve body also serves as a leak detector, by providing a path for fluids passing through the valve to leak to the exterior of the valve body in the event of a failure of the seal between the bonnet and the valve body, which can readily be detected by passersby upon inspection of the exposed end of the bore at the exterior of the valve body.

  • Patent number: 6668853
    Abstract: A pressure relief valve has a gasketed main body fastened to a vessel wall adjacent to a vent port, the body having a recess surrounding the port which receives a plastic insert removably coupled to the body by a retaining ring fastened to the main body. The insert defines a passage communicating with the port and a valve seat engageable by a seal assembly for closing the valve. The seal assembly includes an annular retainer for a seal O-ring and a plug receivable through the retainer and into a socket in a valve stem, which is spring-biased against the retainer and is guided in a guide assembly removably mounted on the main body. The insert is formed of plastic and the retainer and plug may also be formed of plastic and can be readily field-removable by simply unbolting the housing from the vessel and unfastening the retaining ring. The guide and bias assemblies need not be disassembled.

  • Patent number: 6634377
    Abstract: A replacement actuator feed limit valve assembly, which regulates the flow and pressure of automatic transmission fluid within the actuator feed limit hydraulic circuit in an automotive transmission valve body is disclosed. The present actuator feed limit valve assembly comprises a hard anodized valve piston disposed within a mating, full contact valve sleeve having inlet and exhaust ports disposed about its circumference which increases actuator feed limit circuit control, reduces oscillation, and eliminates side loading and bore wear thereby correcting improper gear starts, soft/delayed shifting and clutch/band failure. The present valve assembly also includes fluid directing structures, which reduce the turbulence of hydraulic fluid passing through the valve. By substitution of alternative compression springs provided in an aftermarket kit format, the present replacement actuator feed limit valve assembly will function in either General Motors 4L60E or 4L80E early and late design transmission valve bodies.
