Class Information
Number: 91/505
Name: Motors: expansible chamber type > Three or more cylinders arranged in parallel radial or conical relationship with rotary transmission axis > Cylinders parallel to rotation axis > Stroke control > By varying reaction plate inclination relative to cylinder axes
Description: Apparatus in which the plural cylinders or pistons coact with a common drive transmission element, e.g., swashplate, etc., for converting relative reciprocatory movement of said cylinders and pistons to or from rotary motion of said cylinders or said transmission element, said transmission element, being selectively angularly adjustable relative to said parallel cylinder axes for varying the reciprocatory stroke length between said cylinders and pistons.
