Abstract

A telescoping gear pump comprises a bolt, a Bellville washer, a wear plate, a seal housing, a seal spring, a spur gear including a wear lobe, a seal ring and a case drain path, a shaft, a ring gear including a wear lobe, seal ring, and a case drain path, seal, a bolt assembly including a Bellville washer and bolt, and a pressure plate. The assembly provides pressure to a fluid to maintain a seal within a telescoping pump/motor during operation. The wear lobe reduces wear while maintaining fluid pressure.
