Abstract
A rotary valve rotated by an arm connected to a piston being driven by the pressurized fluid, either water or air. The orientation of the valve body in the valve housing will direct the fluid in one of two directions to move the piston. The arm of the rotary valve is connected to a cam that rotates a shaft connected to the valve body. Two cam rollers are biased towards the outer surface of the rotating cam member. The cam rollers provide a force to the cam to aid in the changing of the orientation of the valve body. There are two bump outs on the cam that correlate to the end of the piston movement so that the rotary valve does not stop at an end point of the piston stroke. The rotary valve may be is utilized in a chemical dosing or chemical application device that is driven by pressurized fluid.
Claims20
A rotary valve for use with a fluid proportioner, the rotary valve comprising:
- a valve housing with an inlet and an outlet;
- a valve body rotatably mounted with the valve housing, the valve body having a shaft extending out of the valve housing;
- a piston configured to move linearly within a cylinder;
- and,
- an arm configured to transfer a linear movement of the piston to a rotational movement of the valve body and rotate the valve body 360 degrees around the shaft within the valve housing.
A rotary valve for use with a fluid proportioner, the rotary valve comprising:
- a valve housing with an inlet and an outlet;
- a valve body rotatably mounted with the valve housing;
- a piston configured to move linearly within a cylinder;
- a cam disposed outside of the valve housing, the cam secured to the valve body so as to provide rotational movement to the valve body;
- and,
- an arm secured to the piston and to the cam and configured to transfer linear movement of the piston to the rotational movement of the valve body such that the valve body completely rotates within the valve housing.
