<p>The injection device has a pump with a supply piston (2) under high pressure in the pump housing (1), connected via a drive punch (15) to the in and out contours of a cam. The supply piston is guided by a spring (3) at its top end. It has a control bush (6) round its lower region, with an angled groove, providing a supply stroke of the second stage via a longitudinal boring (4) and a transverse boring (5) in the supply piston.</p> |
