Abstract
An electric machine for starting an internal combustion engine, comprising a housing (10) having at least one sealing device (14) which seals an interior (10a) of the housing with respect to the surroundings of the housing (10), and at least one pressure reduction device (1), wherein the at least one pressure reduction device (1) is embodied so as to be moveable in a translatory fashion relative to the at least one sealing device (14) in order to form, in the case of an overpressure in the interior (10a) of the housing, at least one venting duct via which an at least partial reduction in pressure is ensured.
Claims9
A starter for starting an internal combustion engine, the starter comprising a housing (10) having at least one sealing device (14) which seals an interior (10a) of the housing with respect to the surroundings of the housing (10), and at least one pressure reduction device (1), characterized in that the at least one pressure reduction device (1) is moveable in a translatory fashion relative to the at least one sealing device (14) in order to form, in the case of an overpressure in the interior (10a) of the housing, at least one venting duct via which an at least partial reduction in pressure is ensured, and wherein the at least one pressure reduction device is integrated into a shaft for rotational movement such as a drive shaft or an output shaft of the starter, and wherein the starter is configured such that the at least one pressure reduction device is moveable automatically in response to an overpressure in the interior of the housing to form the at least one venting duct.
A method for operating a starter (100) for starting an internal combustion engine, the starter comprising a housing (10) having at least one sealing device (14) which seals an interior (10a) of the housing with respect to the surroundings of the housing (10), and at least one pressure reduction device (1) integrated into a shaft for rotational movement such as a drive shaft or an output shaft of the starter, wherein a change in pressure owing to operation takes place in the interior (10a) of the housing, the method comprising carrying out an automatic translatory movement of the at least one pressure reduction device (1) relative to the at least one sealing device (14) in response to an overpressure in the interior of the housing in order to at least partially reduce the overpressure.
