Rotary device having plural mounting orientations and fluid connections

A rotary device for use with fluid, said rotary device comprising:

• a rotor;
• a plurality of vanes connected with said rotor;
• a cam ring extending around said rotor;
• a first end plate disposed adjacent to a first end of said rotor;
• a second end plate disposed adjacent to a second end of said rotor, said first and second plates, cam ring, rotor and vanes cooperating to form a plurality of variable volume working chambers;
• housing means for enclosing said rotor, vanes, cam ring and first and second end plates, said housing means including a main section and a cover section which are disposed in a telescopic relationship;
• one of said sections of said housing means including mounting means for use in mounting said rotary device on a support structure, said main section and cover section of said housing means being rotatable relative to each other to any one of a plurality of orientations to enable said mounting means to be used to mount said rotary device on the support structure with said main section and cover section of said housing means in any one of the plurality of orientations relative to each other;
• fastener means for interconnecting said main section and cover section of said housing means when said main section and cover section are in any one of the plurality of orientations relative to each other;
• a drive shaft connected with said rotor and extending through said cover section;
• seal means connected with said cover section and engaging said drive shaft to block leakage of fluid along said drive shaft;
• an arcuate manifold chamber formed between said cover section and said main section of said housing at a location where said cover section and said main section of said housing are disposed in a telescopic relationship, said arcuate manifold chamber having an extent along a central axis of said drive shaft which is less than the extent of the telescopic relationship between said cover section and said main section of said housing along the central axis of said drive shaft;
• first passage means disposed in said cover section for conducting fluid away from said seal means to said arcuate manifold;
• and
• second passage means disposed in said main section of said housing means for conducting fluid away from said arcuate manifold chamber, said first and second passage means being rotatable relative to each other during rotation of said main section and said cover section of said housing means relative to each other.

A rotary device for use with fluid, said rotary device comprising:

• a rotor;
• a plurality of vanes connected with said rotor;
• a cam ring extending around said rotor;
• a first end plate disposed adjacent to a first end of said rotor;
• a second end plate disposed adjacent to a second end of said rotor, said first and second end plates, cam ring rotor and vanes cooperating to form a plurality of variable volume working chambers;
• and
• housing means for enclosing said rotor, vanes, cam ring and first and second end plates, said housing means including a main section and a cover section;
• said main section of said housing means being cast as one-piece and having a plurality of risers, said plurality of risers include a first riser facing in a first direction, a second riser facing in a second direction which is opposite to said first direction, and a third riser in a facing a third direction which is transverse to said first and second directions;
• each of said risers of said plurality of risers including surface means for defining a recess, said surface means defining a recess in one of said risers of said plurality of risers being machined to facilitate connecting said main section of said housing with a first fluid conduit, said surface means defining recesses in risers other than said one riser of said plurality of risers being in an as cast condition and blocking fluid flow through said risers other than said one riser of said plurality of risers.
