Abstract
The utility model relates to a novel return ring of a radial plunger pump, which comprises a pump cover, a pump body, a valve body, a valve core, a plunger, a big control plunger, a small control plunger, a big slide block, a small slide block, a connecting rod, a stator, a rotor, a transmission shaft, a flow distributing shaft, a shaft coupling and a return ring, wherein three ring surfaces are arranged on the return ring, the first ring surface is in contact with a piston shoe of the connecting rod, the second ring surface and the connecting rod form a friction pair, and the third ring surface is in contact with the stator; the return ring is mounted in the stator and forms a friction pair together with the connecting rod; and the return ring is fixed in the stator by the stator so as to realize that the connecting rod drives the plunger to reciprocate. The novel return ring of the radial plunger pump is made of aluminum bronze ZQA19-4; therefore, the wearing resistance is increased, the lubricating condition is improved and the cost is reduced.
