ABSTRACT:
A positioning mechanism (10) with positioning members (42, 42) is located entirely within a discharge stud (7). The positioning members (42, 43) are intermeshed together through fine threads formed on the members (42, 43). An actuator (20) operates on a return stroke to open an outlet valve (19) for a short time to vent medium spaces (12, 13). The positioning mechanism (10) is adjusted to control the metered discharge of the media. A suction tube (24), a reservior seal (25) and a reservoir fastener (26) are also included within the positioning mechanism (10) in a preassembled unit (30).
