Abstract
Abstract The invention relates to a prime mover of the radial type. The mover is driven by rod-like driving elements which are eccentrically linked to the shaft and are essentially radially directed. The other end of each of the driving elements is connected to a diaphragm of the bellows type which encloses a pressure chamber. The pressure chamber alternately is loaded and exhausted with pressure medium depending on the rotating movement of the shaft thus acting on the driving elements whose oscillating movements are directed to the shaft and transformed to a rotary movement.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
174 words
In a prime mover of the radial engine type having a housing, a shaft rotatably mounted in the housing, a plurality of driving elements extending substantially radially with respect to the shaft axis thereof, means forming a plurality of chambers for fluid fixed with respect to the housing and means to connect said fluid chambers to pressure and exhaust, said chamber forming means including a diaphragm forming the wall of each chamber nearest the shaft axis and means operatively conneCting each diaphragm with one of the driving elements, each diaphragm having a relatively thicker central portion of large area acting as a piston and a relatively much thinner outer portion of substantially less radial extent than the inner portion, said means connecting the diaphragm to the driving element covering only a small part of the central portion, said means for connecting the fluid chambers to pressure and exhaust including passages extending substantially parallel to the shaft axis, said diaphragms having lateral extensions integral therewith forming the walls of such passages nearest the shaft axis.
Claim 2
Dependent Claim
174 words

Claim 3
Dependent Claim
32 words
In a prime mover as claimed in claim 1, distributor valve means turnable with the shaft and radially extending passages connecting the distributor valve means with said passages parallel to the shaft.
