Abstract
An injection device is proposed for internal combustion engines whose vane cell pump has two channels 23, 22. Each channel begins at the end portion of the compression recess 21 and discharges into the congruent openings 24, 25 of the support ring 17 and of the receiving ring 16, respectively. These openings are embodied as grooves and are disposed near the rotary wall 28 of the housing 10 of the injection device.
