1. Executive Summary This report represents the design of a foot pump, Stroke 1, for an automotive manufac- turer. It aims at inflating car tires within the range of 1.5 - 2.0 bar using the Schraeder type valve. The pump features a protective enclosed housing body for the constituent parts and a sliding support bracket for the plunger . The pump cylinder is of the single acting type with a bore of 36mm and stroke 80mm and capable of pressures up to 3 bars.1
Stroke 1 is operated by foot, requiring minimal effort. The design conforms to the Interna- tional Organisation for Standards (ISO) item ISO 22435:20072 and the attachable pressure gauge is accurate to European standard EN 126453
