Abstract (en)
[origin: WO2012028507A1] In order to draw fuel inside a cylinder (5) of a pump unit, a piston (7) is displaced along the cylinder (5) by a spring (10) arranged between a pump body (2) and a support plate (11), which is mounted on the piston (7), and has a seat (14) for inserting the piston (7) through the support plate (11), a seat (15) for engaging the piston (7) in the support plate (11), and a communicating section (16) for allowing the piston (7) to pass between the insertion seat (14) and the engaging seat (15); the communicating section (16) being bounded laterally by two elastically deformable arms (17) each having a respective free end (18).
