    Abstract: The present invention provides a single screw compressor wherein a gap between a screw rotor and a casing can be easily adjusted. A single screw compressor (1) comprises a screw rotor (2) and a casing (3), which houses the screw rotor (2). The outer circumferential surface of the screw rotor (2) has a plurality of helical grooves (6). The screw rotor (2) is a tapered rotor whose outer diameter increases from an inlet side toward a discharge side. The casing (3) comprises an outer tube member (21), which has a circular inner hole, and an inner tube member (22). The inner tube member (22) is fixed to the interior of the outer tube member (21). The inner tube member (22) has a tapered inner surface that opposes the tapered outer circumferential surface of the screw rotor (2).

    Abstract: A rotary-piston internal combustion engine (E1) has an output shaft (1); a rotor (2); a housing (4); an annular operation chamber (5) that is formed by the rotor and the housing, on at least one side of the rotor in the direction of the axis of the output shaft, the annular operation chamber (5) forming an intake operation chamber, a compression operation chamber, a combustion operation chamber, and an exhaust operation chamber; a single pressure applying/pressure receiving member (6) that is provided on the rotor and partitions the annular operation chamber; two operation-chamber partitioning members (7, 8) provided on the housing and partition the annular operation chamber; urging mechanisms that individually urge the operation-chamber partition members toward their advanced positions; an intake port (11); an exhaust port (12); and a fuel injector (14). The pressure applying/pressure receiving member (6) is constructed from a circular arc-shaped partitioning member having first and second slope surfaces. The operation-chamber partitioning members (7, 8) are each constructed from a reciprocating partitioning member that advances and retreats in the direction in parallel with the axis of the output shaft.

    Abstract: A scroll type apparatus for fluid displacement is disclosed. In one embodiment, the apparatus (10) includes an adjustment mechanism (88) capable of being adjusted after assembly of the apparatus to close an axial gap between scroll members (14, 42) and account for manufacturing tolerances in apparatus components. In another embodiment, the apparatus includes an orbital scroll (42) of two portions (44, 46), with a supporting portion (44) surrounding an eccentric bearing (34) of higher density than that of a scroll portion (46). The center of mass of the orbital scroll is thus moved towards the eccentric bearing to reduce torquing of the scroll as it orbits. In a further embodiment, the apparatus includes n orbital scroll (42) having two portions, a supporting portion (44) surrounding an eccentric bearing (34) having a lower coefficient of thermal expansion than that of scroll portion (46), to reduce thermal expansion of the supporting portion, reducing misalignment of the orbital scroll on the eccentric bearing.
