<p>A device for reducing the vacuum in the induction manifold of an engine and supplying additional air to said engine, having a spring-loaded, normally closed, one-way valve adapted to be controlled by the vacuum in the manifold, and a tubing leading from said valve to the manifold of the engine, said valve being substantially loaded by a constant counterforce means and to a smaller extent by spring force, said valve and tubing being arranged to pass air through the valve and tubing to the manifold when the valve is open. In a preferred embodiment, the valve is damped against vibrations.</p> |
