Dispensing tool assembly for evacuating and charging a fluid system |
摘要 |
A fluid dispensing tool assembly includes an upper tool unit having an evacuation port and a fluid inlet port with fluid actuated poppet valves selectively controlling the flow through each port to a center passage within the upper tool unit. The assembly also has a lower tool unit connected to the upper tool unit by a quick-release coupler and includes a center tube member projecting into the passage and also into the inlet portion of a fluid receiving system. The tube member is shifted axially by a fluid actuated piston within the lower tool unit to form a fluid-tight seal with the inlet portion after a second coupler secures the tool assembly to the inlet portion. A fluid-tight seal may be formed between an annular seat on a plastic inlet portion of the receiving system and an annular shoulder on the tube member within the lower tool unit.
