  • Combination battery cover, heat shield and hold down
    Patent number: 6593027
    Abstract: A combination battery cover, heat shield, hold down having preferably formed integrally as one piece with flexible living hinges a pair of battery electrode covers. The cover has a cross channel on the undersurface which communicates with riser channels provided between ribs provided in the battery tray side wall. Apertures are formed between the tray sidewall ribs to provide air to the risers. An air deflector extends outwardly from the tray sidewall to direct air flow to the apertures in the tray. In an alternative embodiment, the electrode caps are attached by separately formed living hinges attached to the caps.

  • Load bearing solenoid operated valve and method of making same
    Patent number: 6588726
    Abstract: A load bearing solenoid operated valve having a one piece body with threads on opposite ends thereof for connection to a system placing the valve in tension or compression. An inlet port is formed in one end of the body and a plurality of cross ports are formed to communicate with the inlet. A sleeve valve/armature member which is magnetizable is slidably received over the body and has radial ports which are moved axially for valving the body cross ports. An annular flux collector ring and a pole piece are disposed on the body on opposite axial sides of the sleeve valve. A bobbin with coil thereon is received over the body and sleeve and a magnetically permeable cover over the coil completes the flux loop about the coil.

  • Solenoid assembly with high-flux C-frame and method of making same
    Patent number: 6219903
    Abstract: A solenoid valve having the valve body formed integrally on one end of the coil bobbin. A C-frame formed integrally from a single piece of sheet stock has at least one of the end of the C-frame deformed over an end of the bobbin and the opposite end thereof received on the opposite end of the bobbin to increase the surface area for flux transfer to a sliding armature within the bobbin for operating a valve obturator. In one embodiment, both ends of the C-frame are each deformed respectively over one end of the bobbin.
