DETAILED DESCRIPTION OF THE INVENTION

[0044] The present invention relates, as mentioned above, to a two-way valve.

[0045] FIG. 1 schematically shows a cross-sectional view of a possible embodiment of the two-way valve object of the present invention.

[0046] The two-way valve comprises a first terminal body (100), a second terminal body (200) and a central body (300).

[0047] The first terminal body (100) and the second terminal body (200) comprise a symmetry of revolution with respect to a longitudinal axis (400) of the two-way valve. In contrast, the central body (300) does not comprise said symmetry of revolution with respect to the longitudinal axis (400) of the two-way valve.

[0048] FIG. 2 and FIG. 3 show respective cross-sectional views of the central body (300) of the two-way valve.

[0049] The central body (300) comprises a first end (301) arranged in correspondence with the first terminal body (100) of the two-way valve, and a second end (302) arranged in correspondence with the second terminal body (200) of the two-way valve.

[0050] In FIG. 2 and FIG. 3, the first end (301) of the central body (300) is shown on the left of the Figure, while in FIG. 1 said first end (301) of the central body is shown on the right of the figure.

[0051] For its part, in FIG. 2 and FIG. 3, the second end (302) of the central body (300) is shown on the right of the Figure, while in FIG. 1 said second end (302) of the central body is represented on the left of the figure.

[0052] The central body (300) comprises a first internal valve (303) or pressure relief valve, and a second internal valve (304) or compensation valve.

[0053] The first internal valve (303) or pressure relief valve is located in a first housing (305) comprising a first valve seat (306).

[0054] The second internal valve (304) or compensation valve is located in a second housing (307) comprising a second valve seat (308).

[0055] FIG. 4, FIG. 5 and FIG. 6 show exploded views of the two-way valve.

[0056] As can be seen, the first internal valve (303) or pressure relief valve comprises a first shutter element (309), a first spring (310) and a first support element (311) configured to support the first spring (310).

[0057] For its part, as can be seen in FIG. 4, FIG. 5 and FIG. 6, the second internal valve (304) or compensation valve comprises a second shutter element (312), a second spring (313), a second support element (314) configured to support the second spring (313), and an interposition element (315) configured as an interposition means between the second spring (313) and the second shutter element (312).

[0058] The first shutter element (309) comprises a spherical geometry and is configured to seal a first internal path (316) of cooling fluid when abutting against the first valve seat (306) of the first housing (305).

[0059] The second shutter element (312) comprises a disc-shaped geometry and is configured to seal a second internal path (317) of cooling fluid when abutting against the second valve seat (308) of the second housing (307).

[0060] Both the first shutter element (309) and the second shutter element (312) are preferably made of elastomeric material.

[0061] Both the first support element (311) and the second support element (314) comprise a base provided with one or more holes (318) or openings, configured to enable the passage of cooling fluid after the first internal valve (303) or pressure relief valve is opened, and the second internal valve (304) or compensation valve is opened respectively.

[0062] The first internal path (316) of cooling fluid is shaped about a first axis (500) of local symmetry, and the second internal path (317) of cooling fluid is shaped about a second axis (600) of local symmetry.

[0063] The first axis (500) of local symmetry of the first internal path (316) of cooling fluid and the second axis (600) of local symmetry of the second internal path (317) of cooling fluid are parallel to each other, and offset in a manner parallel with respect to the longitudinal axis (400) of the two-way valve. Thus, both the first axis of local symmetry (500) and the second axis of local symmetry (600) are eccentrically arranged on opposite sides with respect to the longitudinal axis (400) of the two-way valve.

[0064] Likewise, the first valve seat (306) and the second valve seat (308) are located in different transversal planes of the central body (300).

[0065] The first terminal body (100) of the two-way valve comprises a first cannula (101) or pipette configured to be connected to the inlet/outlet conduit of an expansion chamber of a cooling fluid.

[0066] The second terminal body (200) comprises a second cannula (201) or pipette, configured to be connected to a conduit or hose of a cooling circuit.

[0067] The first terminal body (100) of the two-way valve comprises a first connection area (102) (or connection edge) configured for connecting by means of spin welding with the first end (301) of the central body (300).

[0068] The second terminal body (200) of the two-way valve comprises a second connection area (202) (or connection edge) configured for connecting by means of spin welding with the second end (302) of the central body (300).

[0069] FIG. 7 and FIG. 8 show two perspective views of the central body (300) with the respective first housing (305) and first valve seat (306) for the first internal valve (303) or pressure relief valve, and second housing (307) and second valve seat (308) for the second internal valve (304) or compensation valve.
