  • Patent number: 5172714
    Abstract: A fuel check valve assembly for an automotive vehicle fuel tank includes a valve casing having a valve seat and a float valve movably installed in the valve casing for controlling opening and closing of the valve seat. The float valve consists of a valve float and a valve head cooperative with each other to define therebetween a sealingly closed chamber. The valve head is subjected on opposite sides thereof to a pressure within the sealingly closed chamber and a pressure within the fuel tank, respectively and movable relative to the valve float in response to a pressure differential across the valve head. The valve head is forced to move relative to the valve float and away from the valve seat to open the same when the pressure differential across the valve head is larger than a predetermined value.

  • Patent number: 4415192
    Abstract: A door locking knob which has a knob body including an engaging hole perforated in non-circular cross section, and a rod for insertion into the hole and including cutout surfaces formed therealong and engaging portions at the ends for securely engaging the knob body upon turning of the knob. The knob body has a leg portion, and a pair of guide grooves formed axially on both side surfaces of the leg portion. When the rod is inserted into the engaging hole of the knob body and is turned at 90.degree. to engage the rod with the flat inside surfaces of the engaging hole of the knob body to securely implant the rod at the engaging portions into the side surfaces of the engaging holes of the knob body, so as to eliminate the necessity of internally cutting screw threads in the knob body, mounting of the door locking knob is simplified.
