MULTI-RELEASE CYLINDER PUMP COLLECTOR

摘要

PURPOSE: To miniaturize a collector and minimize losses by providing a rotary pump to collect and discharge a cooling agent, an annular collector to collect a fluid and produce a uniform flow of the fluid and a turning means to turn the fluid. CONSTITUTION: A rotary pump 28 is equipped with an impeller 44 and a means to collect and discharge a cooling agent. An annular collector 50 is located radially outboard of the impeller 44 and has a closed outer periphery 52. A pump discharge collector 40 has a turning means and turns the fluid from the annular collector 50 through a duct 54 to the inside of the discharge pipe 32. Thus, the collectors can be miniaturized and losses can be minimized.
