ABSTRACT:
A gear positive displacement machine has a housing, two gear members, and two bearing members supporting the latter. A gap is formed between an inner wall of the housing and a respective one of the bearing member, the gap increasing in two opposite axial directions. It may start from a central transverse plane of the bearing member. The gap may be formed by a convex peripheral surface of the bearing member or by a convex inner wall of the housing.
