Abstract
Device for supplying fuel to the atomizer of a combustion engine comprises at least a pump to be connected with the atomizer having a piston-bounded pump chamber and an electromagnet for reciprocating said piston. Said device is improved, particularly with regard to the seal of the pump piston, the control and the adjustment of the pumped quantity of fuel, the life-time and the cooling of the device, the compactness and simplicity of construction and/or simplification of maintenance.
Claims9
A device for supplying fuel to at least one atomizer of a combustion engine, in which the pump chamber of at least one fuel pump, arranged in a pump housing has a displacer volume adjustable by control-means, communicates through an inlet valve with a fuel inlet and through an outlet valve with a fuel outlet to be connected with the atomizer of the combustion engine and is limited by at least one displacer body caused to reciprocate by driving means, said control-means comprising at least one wedge-shaped stop actuated by a control-member, said stop being coupled through a piston rod with the piston of a control-cylinder communicating with the inlet manifold of the combustion engine, characterized in that the control-cylinder is centered with respect to a frame holding the pump housing by means of a centering disc extending into the control-cylinder.
A device for supplying fuel to at least one atomizer of a combustion engine, in which the pump chamber of at least one fuel pump, arranged in a pump housing has a displacer volume adjustable by control-means, communicates through an inlet valve with a fuel inlet and through an outlet valve with a fuel outlet to be connected with the atomizer of the combustion engine and is limited by at least one displacer body caused to reciprocate by driving means, said control-means comprising at least one wedge-shaped stop actuated by a control-member, said stop being coupled through a piston-rod with the piston of a control-cylinder communicating with the inlet manifold of the combustion engine, characterized in that at the end of the control-cylinder remote from the stop an axially displaceable switch is provided for stopping the pump at a drop below a given pressure in the inlet manifold.
A device for supplying fuel to the atomizer of a combustion engine comprising at least one pump to be connected with the atomizer having a pump chamber limited by a piston and driving means for causing the piston to reciprocate, said driving means comprising an armature energized by at least one electro-magnet and adapted to reciprocate between stops characterized in that at least one of the stops is adjustable in accordance with the speed of the engine.
