A fluid operated, reciprocatory rotary motor, comprising in combination, a body having a cylindrical bore therein, first and second head assemblies fixedly mounted to said body over the respective ends of said bore, a shaft extending through said bore and through said head assemblies, a radially disposed, longitudinal stator mounted in said body between said head assemblies, first and second annular thrust bearings respectively disposed in said first and second head assemblies, said shaft being journalled in said bearings, a radially disposed, longitudinal vane fixedly mounted to said shaft and extending from said first head assembly to said second head assembly, first sealing means carried by said stator for sealing said stator to said shaft and to said head assemblies, second seal means carried by said vane for sealing said vane to said body and to said head assemblies, and means for admitting fluid under pressure into said bore to one side or the other of said stator, said first head assembly including a head member having a central bore and a counterbore through which said shaft extends, an annular thrust bushing compressed between an annular shoulder on said shaft and said first thrust bearing an annular end plate compressed between an annular end surface of said body and an annular facial surface on the inner side of said head, the radius of said facial surface being less than the radius of said annular end surface, and an annular sealing member compressed between said thrust bushing and the inner diameter of said end plate.
