Abstract

837,728. Rotary motors. ALLMANA SVENSKA ELEKTRISKA A.B. Oct. 7, 1958 [Oct. 15, 1957], No. 31926/58. Class 110 (2). A rotary hydraulic motor of the oscillating curved piston type comprises concentric cylinders which are each subdivided by a partition 15 or 25 and are provided with a pair of pistons 11, 12 or 21,22. The pistons may operate a valve, a door or a rudder shaft 40 through a tiller 30 which freely engages the ends 18, 28 of the pistons and extends above the top of the cylinders (see Fig. 1, not shown). The cylinders are of rectangular cross-section and have a common side wall 31.
