Abstract
A rotary piston machine that includes a casing with a drive shaft that connects to an annular body having arc-shaped segments having swivelling fulcrums that hold slidable vanes which define chambers of varying size within said casing together with inner and outer rings that are each integral with a vane, and movable relative to each other within a ring stack (30), the axis of the ring stack being parallel to the drive shaft axis but offset so that said vanes assume varying angular positions as they revolve.
Claims14
A rotary piston machine (1) comprising in combination
- (a) a casing (12, 40, 60),
- (b) a central annular body (20) mounted for rotation within said casing (12, 40, 60) said central annular body (20) comprising a cylindrical array of arc-shaped elements (24),
- (c) a drive shaft (18) supported by said casing (12, 40, 60) and coaxially joined to said central annular body (20) so as to rotate said central annular body (20) about a first axis (M),
- (d) swiveling fulcrum slides (28) located in said arc-shaped elements (24), which slides are parallel to said first axis (M),
- (e) a plurality of ring and vane members (a-f) mounted in a stack (30) in said casing (12, 40, 60) for rotation around a second axis (A) that is offset from said first axis (M), said ring and vane members:
- (i) each comprising a pair of concentric rings including an inner ring (32) and an outer ring (36),
- (ii) each comprising a vane (34) that extends between and is integral with both the inner ring (32) and the outer ring (36) of each ring pair, each vane (34) being slidable within one of said swiveling fulcrum slides (28) so as to thereby define a plurality of separate and spaced apart chambers (k) within said casing (12, 40, 60),
- (iii) being peripherally offset and movable relative to each other within said ring stack (30),
- (iv) being stacked by intervals of at least one ring width (w) each.
