  • Patent number: 4502510
    Abstract: A fluid system is disclosed having a passage with a reduced diameter orifice. A wire extends into the orifice and is reciprocated therein to simultaneously clean and meter a predetermined fluid flow through the orifice.

  • Patent number: 4212557
    Abstract: An automatic roller-type hub clutch is provided with a manual device operable to override the automatic mechanism to prevent free wheeling due to overrun. An improved resilient coupling is provided for the manual device designed to translate rotational movement from a rotatable selector to a camming device and to provide a built-in self energizing action in both an engaging and disengaging direction. The resilient coupling disclosed is a coiled torsional spring having one end connected to the rotatable selector and the opposite end connected to the camming device. In operation, the rotatable selector is rotated in opposite directions to wind and unwind the spring causing the camming device to rotate with the rotatable selector to axially move a slidable clutch member into engagement with a fixed clutch member.
