Squeezebulb operated sports ball pump

摘要

A flexible, highly portable pump is designed for volleyball players but has wider applications. Motive force is delivered from a squeezebulb having a check valve at each end and communicating downstream to a fitting which will accept a ball inflation needle. A deflation valve is located in the air passageway downstream from the squeezebulb outlet check valve. The pump is designed so that it can be stuffed into a back pocket or thrown in a sports bag, and is flexible enough to be bent in two or wadded up and stuffed anywhere. The squeezebulb and relief valve are adapted for one-handed operation, and an optional one-piece solid state pressure gauge can be integrated into the body of the pump.
