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.

The invention relates to a magnetic drive device enabling a member placed one side of a non-magnetic wall to be driven by a rotary drive shaft placed on the other side of the wall. The driven member is mounted to rock about an oscillation axis orthogonal to the axis of rotation of the drive shaft and carries an axially-magnetized magnet whose outside surface has a right cross-section in the plane containing the oscillation axis and the axis of rotation of the drive shaft that is in the form of a circle centered on the oscillation axis. The drive shaft carries an axially-magnetized magnet offset from the axis of the drive shaft.
