Abstract
A float controlled valve has a float chamber for accumulating a fluid, a pivoting float arm having a float mounted on one end thereof for fluid level determined movement within the chamber, a pivotally mounted actuator arm coupled to the float arm by a magnet driver and having a first magnet mounted at one end of the actuator arm; a pivotally mounted control arm having a second magnet attached thereto, in magnet coupling relationship with the first magnet, and valve means coupled to the pivotally mounted control arm for controlling fluid flow from the chamber in response to movement of the float.
Claims33
A float controlled valve comprising:
- a float chamber for accumulating a fluid;
- a pivotable float arm mounted on first fixed pivot means and having a float mounted thereon for fluid level determined movement without the chamber;
- a pivotally mounted actuator arm mounted on second pivot means spaced from the first pivot means, coupled to the float arm and having a first magnet mounted at one end of the actuator arm;
- a pivotally mounted control arm having a second magnet attached thereto in magnetic repelling coupling relationship with the first magnet;
- and
- valve means coupled to the pivotally mounted control arm for controlling fluid flow from the chamber in response to movement of the float.
A float controlled valve comprising:
- a float chamber for accumulating a fluid;
- a pivotable float arm mounted on first fixed pivot means and having a float mounted thereon for fluid level determined movement within the chamber;
- a pivotally mounted actuator arm mounted on a second pivot spaced from the first fixed pivot means and coupled to the float arm and having a first magnet mounted at one end of the actuator arm;
- a pivotally mounted control arm having a second magnet attached thereto in magnetic repelling relationship with the first magnet with like poles in close proximity;
- first and second colinear opposed valve assemblies;
- and
- valve shuttle means disposed between the first and second valve assemblies, and coupled to the pivotally mounted control arm for alternately opening one valve assembly and closing the other, depending upon the position of the control arm.
A pressure operated pump comprising:
- a pressurizable pump chamber for accumulating a fluid;
- a pivotable float arm mounted on a first fixed pivot means and having a float mounted thereon for fluid level determined movement within the pump chamber;
- a pivotally mounted actuator arm mounted on a second pivot means spaced from the first fixed pivot means and coupled to the float arm and having a first magnet mounted at one end of the actuator arm;
- a pivotally mounted control arm having a second magnet attached thereto in magnetic repelling coupling relationship with the first magnet;
- a source of pressurized air;
- and
- valve means coupled to the pivotally mounted control arm and connected between the source of pressurized air and the pump chamber for controlling pressurization of the chamber from the source of pressurized air in response to movement of the float.
