Abstract

The fuel injection impulses are taken from the fuel dribble collection pipe (2) by a plastic housing containing a fuel pressure chamber (4) and a thin diaphragm (3). The diaphragm transfers the impulses to a piezo-ceramic plate (5) contained in a metal housing provided with a connection plug (8). The plug is formed as a co-axial connector leading to an electronic circuit. The circuit consists of an amplifier, a rectifier and a comparator with an adjustable trigger threshold. A monoflap is provided when used with a display scale.
