摘要： A crescent member is disclosed which is configured to be in constant contact with outer and inner gear teeth to prevent unwanted fluid backflow between the gears. The crescent member may be part of a low-pressure fuel pump system for a diesel engine. In order to reduce heat buildup in the crescent member and gear teeth, the crescent member comprises a gap to allow fluid to flow within the crescent member to absorb and dissipate the heat generated by friction. The crescent member is resilient to maintain constant contact, but flexible enough to reduce wear from friction over time.
