摘要：
A positive displacement rotary pump based on the spiral principle in which the piston is given a complex orbital motion by a crankshaft drive, the piston being also pivoted to a second guide element, this pivot point reciprocating along an open path. The second guide element is constructed to provide compactness and ease of manufacture.
