Abstract
An injection pump comprises several modules in a housing. Each module has a chamber supplying an injection circuit, separated by a deformable diaphragm from a compartment defined by a bore of the housing and by a reciprocating piston. The chamber is connected to a fuel supply and is connected to the injection circuit by a non-return valve. The pressures of the liquid in each compartment are adjusted independently. All pistons are driven by a same cam.
