ABSTRACT:
A pump for moving a fluid has a housing with a internal chamber accommodating a pair of rotating pistons. Each piston has protrusions that register with pockets in the other piston in non-contact relation as the pistons rotate. A fluid accumulator in fluid communication with the pump holds a supply of fluid to prevent excessive pressure rise.
