INFLATION DEVICE

摘要

An inflation device for inflating containers having a body with an air channel therein being in the form of a venturi tube. A first inlet is provided in the body, being in communication with the air channel, to allow compressed air to flow into the air channel. An outlet is provided in the body, being in communication with the air channel, to allow the air to exit the air channel for inflating a container joined to the outlet. A second inlet is provided in the body, being in communication with the first inlet, to allow ambient air to be sucked into the air channel as a result of the compressed air flowing in the air channel and passing through the venturi tube. A self-closing valve is located at the second inlet for closing off the second inlet if the pressure in the air channel is greater than the ambient pressure. The inflation device further has a sensor means being adapted to continuously measure the pressure in a container joined to the body and a manually operable valve for interrupting the supply of compressed air into the air channel.
