Abstract
This cold-start injector for internal combustion engines is adapted to be connected to the induction manifold of the engine and comprises essentially a normally closed needle valve controlling the delivery of fuel and a solenoid for actuating said needle valve adapted to be inserted in series with the manual switch controlling the starter motor of the engine. Said needle valve or other movable member of the solenoid bears through a spring against a fluid-type damping capacity comprising a pair of movable walls and, between said walls, a fixed partition having a throttling orifice, said spring reacting against one of said movable walls, the other wall co-acting with the movable member of a normally closed electric switch disposed in series in said circuit and adapted to be opened by means of said damping capacity.
