The alloy is for making an infrared transducer. It is constituted by (In,Tl,) (As,Sb,) in which 0&lE;x<1 and 0<y<1 (where x and y are less than &frac12;). On a GaSb or AlSb substrate, the transducer comprises an active layer of the alloy having a composition such that its lattice is of a size that is equal to that of the substrate material.

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.
