Abstract: The gear machine comprises a housing in which two gears mounted on shaft journals mesh. The shaft journals are supported in bushing or eyeglass-shaped bearing members. Located between the latter and the lateral surfaces of the gears are sealing plates which are brought into sealing contact with the lateral surfaces of the gears by axially-acting pressure fields. Relief grooves are formed circumferentially in the outer circumference of the bearing members and are spaced from and adjacent to the sealing plates. These relief grooves communicate with the low-pressure sdide of the gear machine and attain an optimal sealing action.
