A plunger (52) having a cylindrical body with a smooth surface (61) thereon which joins an semi-spherical atmospheric seat (62) with a conical surface (60) to define with a section (31) of bore (30) a flow path through which air is communicated from the environment to a rear chamber (20) without the creation of noise.
