Abstract
A float assembly comprising a float traveling along a rod until making contact with either an upper or a lower adjustable stopper, so that an actuator lever having one or more counterweights in mechanical coupling with a switch, so that the float assembly may respond to the fluid level.
Claims16
A float operated electric switch actuating mechanism comprising:
- an electric switch;
- a float having a notch along said float's outer perimeter, said notch traveling along an assistive rod;
- a spiral rod connected to a frame that limits the displacement of said spiral rod in a vertical dimension while allowing said spiral rod to rotate freely around said spiral rod's central axis in response to said float's up/down movement, with said spiral rod having an adjustable upper and adjustable lower stopper that cause said spiral rod to move up/down in response to said float force on said upper/lower stoppers respectively;
- and
- a cross beam mechanically connected to said electric switch and to said spiral rod through a rotating mechanical component so that as the float pushes the upper/lower stopper, the resulting cross beam movement activates/deactivates said switch.

A float operated electric switch actuating mechanism comprising:
- an electric switch;
- a float;
- a hollow rod having two rotatable screws along said hollow rod's length, each said screw having a notch along the length of said hollow rod's outer surface, said notch partially exposing said hollow rod's interior for a given length of hollow rod;
- each said notch having a limit tab with an opening that matches the screw thread, so that rotation of said screw causes the tab to travel along said notch length, one said first tab forming an upper tab, and another said tab forming a lower tab;
- wherein said hollow rod is connected to a frame that limits the displacement of said hollow rod in a vertical dimension in response to said float's contact with either said upper or a lower tab;
- a cross beam mechanically connected to said electric switch and to said hollow rod through a rotating mechanical component so that as the float pushes the upper/lower stopper, the resulting cross beam movement activates/deactivates said switch.

A float actuating mechanism comprising:
- a fluid flow actuator;
- a float having a notch along said float's outer perimeter, said notch traveling along an assistive rod;
- a spiral rod connected to a frame that limits the displacement of said spiral rod in a vertical dimension while allowing said spiral rod to rotate freely around said spiral rod's central axis in response to said float's up/down movement, with said spiral rod having an adjustable upper and adjustable lower stopper that cause said spiral rod to move up/down in response to said float force on said upper/lower stoppers respectively;
- and
- a mechanical member mechanically connected to said fluid flow actuator and to said spiral rod through a rotating mechanical component so that as the float pushes the upper/lower stopper, the resulting cross beam movement activates/deactivates said fluid flow actuator.
