摘要
A sealed, pouch-like envelope (1) made from a flexible material such as rubber or plastics film has an inlet (2) and outlet aperture (2a), each with its own valve (3). The inlet and outlet connections (2,2a) are joined to each other by a rigid hollow connecting piece (4) which has an opening (4a) for connection to the envelope (1). USE/ADVANTAGE - A simpler, cheaper and more compact means of inflating balls, etc. than using a conventional pump.
