ABSTRACT:
The present invention provides a self-powered proportioner which can automatically, proportionally mix two fluids in a low ratio. A fluid gating means is disposed intermediate a fluid supply and a motor piston to cause reciprocating movement of the motor piston within a motor cylinder. A connecting rod secured to the motor piston is disposed within a cavity in the housing extending between the motor cylinder and a slave pump cylinder. A slave pump piston is secured to the connecting rod for providing responsive reciprocatory movement of the slave pump piston within slave pump cylinder for pumping a second fluid. A connecting rod seal is interposed between the cavity wall and the connecting rod intermediate the motor cylinder and the slave pump cylinder preventing fluid communication through the cavity between the motor cylinder and the slave pump cylinder.
