<p>Circulating type machine has a rotating jacket and eccentric piston which has a piston and several plate type output parts which are in an oscillating manner connected with the jacket, and are fitted at the opposite end with a rotary oscillating headpiece as in 1929744. The straight laminated headpiece has at either end, a crescent shaped configuration which combined with a guide piece, contacts co-axially the convex shaped part of the delivery end of the machine. These convex curved surfaces of the delivery end parts have a shorter arc length than the concave curved part of the guide surface. This ensures a rigid support for the piston hub part. In an alternative arrangement two plate type parts with crescent shape head pieces may be fitted in a transverse manner.</p> |
