Abstract

A hand pump for tyres has a main tube with a plug at one end, and with a bush at the other end slidable over an inner tube. This inner tube has a buffer spring and a connection for the tyre inflator. The other end of the inner tube carries a compression piston. Air trapped behind the piston is forced through a ball valve inside the piston carrier block, through a third tube inside and to the tyre. Between these two inner tubes is a fourth tube and part of the air is forced through a hole in the third tube, and against a plug on the fourth tube. The plug is pushed backwards so that a mark on its outside travels along a graduated slot, thus indicating the pressure of the compressed air.
