Fluid Metering Systems Manufacturers

Fluid metering system includes a housing having a piston chamber with first and second spaced ends and at least one housing inlet and outlet passage. The housing inlet and outlet passages communicate with the piston chamber. A piston is disposed in the piston chamber for reciprocal movement between the first and second ends of the piston chamber to alternatingly define first and second volume. At least one first slot, and second slot are formed on the outer surface of the piston, and extend from respective ends of the piston toward the respectively opposite ends. The piston is rotatable within the piston chamber to alternatingly bring one of the first or second slots in registration with the housing inlet passage, while simultaneously bringing the other of the first or second slots in registration with the housing outlet passage.
