ISOLATED CHAMBER PUMP WITH RECIRCULATION OF LEAKAGES

Abstract

Vibrating pump for liquids comprising a hydraulic system (2) consisting of a hydraulic head (3) with an inlet (4) and an outlet (5) for the liquid, said hydraulic head (3) is joined by the screws (21) to the electromagnetic system (1) composed of the metal frame (7) which integrates the rear bolt (8) and it is situated around the coil (6) which at its turn is located around the bushings (9, 10, 11) constituting the force chamber (12) through which the magnetic core (13) positioned between two springs (27, 28) moves in axial direction and alternative sense and said magnetic core (13) extends in the plunger (14) inside the compression chamber (15) through the leak recovery chamber (16).

The leak recovery chamber (16), which is limited by the pressure seal (17) on the right-hand side and by the sealing seals (18, 19) on the left-hand side, recovers any losses of water from the compression chamber (15) and conduct it through the conduit (20) to the inlet (4) of the compression chamber (15) which draws in and re-infuses the water from the leak recovery chamber (16) to the compression chamber.

DETAILED DESCRIPTION

[0024] In the exemplary embodiment shown in FIG. 1 the vibrating pump for liquids comprises a hydraulic system (2) consisting of a hydraulic head (3) with an inlet (4) and an outlet (5) for the liquid, said hydraulic head (3) is joined by the screws (21) to the electromagnetic system (1) composed of the metal frame (7) which integrates the rear bolt (8) and it is situated around the coil (6) which at its turn is located around the bushings (9, 10, 11) constituting the force chamber (12) through which the magnetic core (13) positioned between two springs (27, 28) moves in axial direction and alternative sense and said magnetic core (13) extends in the plunger (14) inside the compression chamber (15) through the leak recovery chamber (16).

[0025] According to the invention, and as shown in FIG. 1, the leak recovery chamber (16), which is limited by the pressure seal (17) on the right-hand side and by the sealing seals (18, 19) on the left-hand side, recovers any losses of water from the compression chamber (15) and conduct it through the conduit (20) to the inlet (4) of the compression chamber (15) which draws in and re-infuses the water from the leak recovery chamber (16) to the pumping circuit.

[0026] In the exemplary embodiment shown in FIG. 2, the leak recovery chamber (16), which is limited by the pressure seal (17) on the right-hand side and by the membrane (22) on the left-hand side, recovers any water losses from the compression chamber (15) and conduct it through the conduit (20) to the inlet (4) of the compression chamber (15) which by suction re-injects the water present in the leak recovery chamber (16) inside the pumping circuit.

[0027] In the exemplary embodiment shown in FIG. 3 the pumping means is composed of a core (13) made of a ferromagnetic material and a plunger (14) attached to said core (13) by over-moulding with a plastic material (23) resulting in a single piece. The plunger (14) is made of ceramic material.

[0028] In the exemplary embodiment shown in FIG. 4 the pumping means is composed of a core (24) made of ferromagnetic material, a plastic washer (25) and a plunger (26) attached to said core (24) by contact cement constituting a single piece. The plunger (26) is made of ceramic material.

[0029] Having described the nature of the invention sufficiently, as well as a preferred version, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the elements described can be changed, provided this does not involve an alteration of the essential features of the invention claimed below.
