Document Type and Number:
Japanese Patent JPH11247783
Kind Code:
A
Abstract:
To optimize a load of a blade, prevent inclination of a blade and suppress abrasion thereof in a fluid machine.
A spiral blade 33 is reciprocably attached to a spiral groove 31 formed on an outer periphery of a roller 21 which can relatively be rotated to a cylinder 17, for determining a space between the cylinder 17 and the roller 21 into a plurality of operation chambers 35. A spacing (e) between an axis of the cylinder 17 and an axis of the roller 21 is 5 mm or less. A load to be applied to the blade 33 can thus be optimized.
