摘要
A lubricating-grease pump includes a pumping chamber, a leakage accumulation chamber, a seal configured to substantially seal the pumping chamber from the leakage accumulation chamber, at least one outlet from the pumping chamber, and at least one leakage-recovery arrangement configured to guide a quantity of grease that has leaked from the pumping chamber into the leakage accumulation chamber back into the pumping chamber. The leakage-recovery arrangement may include a first passageway connecting the leakage accumulation chamber to a storage region, a second passageway connecting the first passageway to the pumping chamber and a spring-biased piston in the storage region.
