First Claim
Patent Images
1. A peristaltic pump comprising:
- an electric motor;
a flexible tube arranged along a substantially circular path; and
a rotatable compression member disposed adjacent to said flexible tube for progressively and recurrently compressing said flexible tube, said compression member including an integrally formed speed-reduction drive means coupled to said electric motor;
wherein said compression member comprises a blocklike cam, a leaf spring disposed at an end of said cam, and a rigid substantially circular cylinder loosely surrounding said cam and said leaf spring.

Abstract
A peristaltic pump, which includes a flexible tube arranged along a circular path and in which a compression member is driven by an electric motor via a gearing, is to be compact and easy to manufacture, so that it can be produced at such a low cost as to be also suitable for applications where it has previously been too expensive. To accomplish this, parts of the pump are combined with parts of the gearing.
