Rotary motion transformer

摘要: A rotory motion transformer (10) is disclosed which has a cylindrical housing (12) and rotatable shaft (36). cam (14) having ascending descending segments (22-28) forming lobes (30, 32) included in the axially aligned with shaft. Equal angular pistons (42-48) are spaced about (36) keyed therewith while remaining slidable thereto. The have helicoid faces on surfaces facing (14), mating of (14). Spring means (52-58) provided to bias against When rotate over surface space between each piston increases decreases volume periodically for rotation. Intake port (15, 16) adjacent provide fluid flow into rotary (10). Exhaust (17, 18) removing from spaces regularly opened closed intake ports exhaust transfer accomplish desired pump air motor action.
