Abstract
A rotary mechanism (10) has an annular (chamber 12) defined by an inner wall (16) of housing (11). A symmetrical two lobed rotor (15) has opposing side faces (21a,21b) a longitudinal axis between apices (22). A drive shaft (50) eccentrically rotates rotor by a block (51) and slot (52) receprocating arrangement and a second supporting means (53). The centre of the rotor follows a circular orbit in the chamber (12). The apices (22) continuously sweep the inner wall (16) creating cavities (25) of successively increasing and decreasing volumes with associated fluid inolet and exhaust port (31, 35).
Claims26
A rotary mechanism comprising:
- a housing defining a substantially annular enclosed chamber with an inner wall;
- a two-lobe symmetrical rotor having a central longitudinal axis between apices of the rotor, the rotor being disposed within the chamber so as to eccentrically rotate within the chamber in such a manner that the apices continuously sweep the inner wall thereby creating cavities between each lobe and the inner wall of successively increasing and decreasing volumes, wherein the rotor is mounted on a single shaft extending through opposite ends of the chamber, the shaft carrying a first guiding means defined by a block mounted for reciprocal movement relative to an elongated slot located on the rotor, whereby the block and shaft allow for eccentric rotation of the rotor;
- spaced inlet and exhaust ports for the supply and discharge of fluid into the cavities;
- and
- a second guiding means that interacts with the first guiding means to guide the rotor and ensure the apices, during operation, are in continuous sealing contact with the inner wall to cause a centre of the rotor to follow a circular orbit in the chamber, wherein the second guiding means is centred offset to a central axis of the chamber.

- a circular guide disc mounted at, at least, one end of the annular chamber;
- and
- a corresponding circular recess on one side of the rotor to receive the guide disc, wherein the recess has its origin at the centre of the rotor and is larger than the guide disc to allow the circular recess to revolve around the guide disc.
