Abstract: An apparatus for dispensing a repeatable volume of flowable material. The apparatus comprises a fluid cylinder body, a piston, a meter body, and at least one valve. The fluid cylinder body includes a fluid chamber, a fluid supply, and a pair of fluid pressure channels. The meter body is positioned adjacent the fluid cylinder body and includes a displacement chamber, a flowable material supply, an outlet valve, an inlet valve, and a flowable material outlet. The piston defines a piston head and a piston stem. The piston head is positioned within the fluid chamber and the piston stem extends laterally from the fluid chamber into the meter body. The valve is positioned adjacent the fluid cylinder body. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
