Abstract
A gear machine includes a machine casing closed by two covers and within which two gear wheels provided on respective shafts supported by bushes are in mutual engagement. A compensation area for the axial thrusts to which a bush is subjected is defined between an elastic diaphragm installed between the bush and a cover, so that because of the clearance between the gear wheels and bushes rapid starting is possible even under load, whereas as pressure increases a corresponding flexure of the diaphragm towards the bushes occurs, so as to gradually narrow clearance while at the same time partially balancing the axial thrusts.
