Transmission for a motor vehicle

A transmission (1) for a motor vehicle, comprising:

• an oil sump (2);
• at least one oil bunker (3 through 5) arranged separated from the oil sump (2);
• and
• a valve (101;
• 201;
• 301) comprising a channel body (102;
• 203;
• 302), at least one sump port (106 through 108;
• 215;
• 306, 307), at least one bunker port (103 through 105;
• 206 through 209;
• 303, 304), a mechanical actuating element (109;
• 219, 220;
• 308, 309), and a hollow cylindrical valve housing (311),
• wherein the channel body (102;
• 203;
• 302) has at least one oil duct (113 through 115;
• 212;
• 319, 322),
• wherein the at least one oil duct (113 through 115;
• 212;
• 319, 322) connects the at least one bunker port (103 through 105:206 through 209;
• 303, 304) to the at least one sump port (106 through 108;
• 215;
• 306, 307),
• wherein the mechanical actuating element (109;
• 219, 220;
• 308, 309) is configured for temperature-dependently deforming such that the mechanical actuating element (109;
• 219, 220;
• 308, 309) transfers the valve (101;
• 201;
• 301) from a closed state into at least one opened state,
• wherein the at least one oil bunker (3 through 5) is connected to the oil sump (2) via the at least one bunker port (103 through 105;
• 206 through 209;
• 303, 304), the at least one oil duct (113 through 115;
• 212;
• 319, 322), and the at least one sump port (106 through 108;
• 215;
• 306, 307) when the valve (101;
• 201;
• 301) is in the at least one open state,
• wherein the at least one oil bunker (3 through 5) is not connected to the oil sump (2) via the valve (101;
• 201;
• 301) when the valve (101;
• 201;
• 301) is in the closed state,
• wherein the channel body (302) is rotatably accommodated within the valve housing (311),
• wherein the channel body (302) comprises a cylindrical portion (318) forming a first bunker port (303) and a second bunker port (304) of the at least one bunker port,
• wherein the channel body (302), in an interior of the channel body (302), forms a first oil duct (319) of the at least one oil duct that connects the first bunker port (303) of the at least one bunker port to a first sump port (306) of the at least one sump port,
• wherein the channel body (302), in the interior, forms a second oil duct (322) of the at least one oil duct that connects the second bunker port (304) of the at least one bunker port to a second sump port (307) of the at least one sump port,
• wherein the valve (301) is shaped such that oil out of the at least one oil bunker (3 through 5) impacting the valve (301) in the axial direction (x) is directed to the first bunker port (303),
• wherein the valve (301) is shaped such that oil out of the at least one oil bunker (3 through 5) impacting the valve (301) in the radial direction (r) is directed to the second bunker port (304),
• wherein the mechanical actuating element (308, 309) is configured for temperature-dependently deforming such that the mechanical actuating element (308, 309) turns the channel body (302) out of a closed position into at least one open position,
• wherein the valve (301) is in the closed state when the channel body (302) is in the closed position, the valve housing (311) covers both the first and second bunker ports (303, 304) such that neither of the first and second bunker ports (303, 304) is connected to the at least one bunker (3 through 5) and oil cannot flow out of the at least one bunker (3 through 5) via the valve (301) into the oil sump (2) when the channel body (302) is in the closed position, and
• wherein the valve (301) is in the at least one open state when the channel body (302) is in the at least one open position, the at least one bunker port (303, 304) is connected to the at least one bunker (3 through 5) via the valve housing (311) such that oil is flowable out of the at least one bunker (3 through 5) via the valve (301) into the oil sump (2) when the channel body (302) is in the at least one open position.
