Abstract: The present invention is a fluid machine constituted so as to close moving spaces communicating with an intake opening by at least one pair of members, move them toward a discharge opening and discharge fluid sucked into the intake opening from the discharge opening. The members are arranged so as to form a specific clearance at a position where they are closest to each other, and a leakage prevention mechanism consisting of short fibers is provided on at least one side surface of the members closing the moving spaces.

Abstract: A scroll type fluid machine includes a housing, a first scroll unit arranged rotatably in the housing and a second scroll unit rotating with rotation of the first scroll unit and gyrating relative to the first scroll unit to vary volumes of compression spaces. The first scroll unit includes a first wrap group including two end plates with support shafts supported rotatably by the housing and scrolled wraps arranged uniformly. The second scroll unit includes a cylindrical outer peripheral ring portion held slidably between the end plates of the first scroll unit, a connection block portion located in a center portion and a second wrap group having plural scrolled wraps extending from the ring portion to the connection block portion to define insertion spaces into which the wraps of the first wrap group are inserted and, with the first wrap group, forming compression spaces.
