Trigger-actuated elastomeric pump

Trigger-actuated elastomeric pump

A trigger-actuated elastomeric pump employs slanting resilient partitions 34, 35 for one-way valving. The pump has a stop 28 formed in its interior at a location adjacent the downstream side of the inlet partition 34 and adapted to prevent the inlet partition from inverting during the pumping action...

Zusammenfassung:A trigger-actuated elastomeric pump employs slanting resilient partitions 34, 35 for one-way valving. The pump has a stop 28 formed in its interior at a location adjacent the downstream side of the inlet partition 34 and adapted to prevent the inlet partition from inverting during the pumping action, which would subsequently render the pump inoperative. Through the use of the stop, the pump can handle greater pressures without concurrent increase in likelihood of failure.
