Abstract
A pump (1) comprising a lubricant reservoir (3) which feeds at least one pumping element (2), the reservoir (3) being delimited by a base (4) in correspondence with which, inside the reservoir (3) there is a rotating spatula (5) featured, equipped with at least one blade (5A) which, by rotating over the base (4), conveys the said lubricant towards an intake (2A) in the said pumping element (2) pushing the said lubricant through a plurality of passages (4A) made in the surface of the said base (4).

A pump (1) comprising a lubricant reservoir (3) which feeds at least one pumping element (2), the reservoir (3) being delimited by a base (4) at which, inside the reservoir (3) a rotating spatula (5) is provided, the spatula (5) being equipped with at least one blade (5A) which, by rotating over the base (4), conveys said lubricant towards an intake (2A) of said pumping element (2) pushing it through a plurality of passages (4A) made on the surface of said base (4), the pump having a flap (8) hinged along a first axis (B) substantially perpendicular to an axis (A) of rotation of the spatula (5), a free end of the flap (8) facing said base (4), the flap (8) providing a movable element (9) able to cooperate with a fixed element (10) of a proximity sensor (20), so as to activate the proximity sensor (20) when said free end of the flap (8) approaches said base (4) thus signaling a minimum level of lubricant (L) inside the tank (3), said flap (8) being supported by said spatula (5).
