Japanese Patent JPS60124589
Kind Code:
U
Abstract:
A housing of the gear motor accommodates a pair of meshing gears which are rotatably mounted in the interior of the housing and which each have a first and a second axial end face. Sealing elements are provided which are located proximal to the respective axial end faces, and an arrangement is provided for forming first fluid-pressure fields which press the sealing elements against the axial end faces. Adjacent at least one of these sealing elements there is provided a space in which an auxiliary fluid pressure field can develop, and an arrangement is provided by means of which the space can be pressurized when it is desired to form therein the auxiliary fluid pressure field so that the same may exert auxiliary pressure upon the associated sealing element to aid in pressing the same against the respective axial end face, and by means of which the space can be vented when such auxiliary pressure is not desired.
