Abstract
The injection device comprises: an ejection chamber (31) with an ejection piston (50) extended by a rod (32), an intermediary chamber (23), passage means (19, 20, 33) between the ejection chamber and the intermediary chamber and between the intermediary chamber and a reserve for said material, a valve (15, 16), actuated by said rod, allowing the opening of the passage between the intermediary chamber and the ejection chamber during at least the final part of the backward motion of the ejection piston and to interrupt said passage during the final part of the ejection motion of the ejection piston, means to bring to depression conditions (24, 29) the ejection chamber with respect to the intermediary chamber during said final part of the backward motion of the ejection piston so as to provide the filling of said ejection chamber, a seat (6) intended to receive a reserve of said medicinal material and driving means (34, 35, 36) for operation of the ejection piston.
