Abstract (en)

The pressurising pump consists of a body (6) defining a chamber (7) in which moves axially, a piston (8) connected to a rod (9) whose movement is controlled by a motor. Inlet to the pump of the fluid is via the portion (10) and outlet is via the porting (11) from whence it is fed to an applicator (3). The pump is characterised in that its external face (14) is enclosed in a jacket (16) which forms a space (18) between this face (14) and the inner wall (17) of the jacket (16). The jacket is fixed in a removable fashion at the points (15). A fluid can circulate in this space (18) via connection pieces (20). <IMAGE>
