Abstract: A dual-chamber syringe has a plunger within an inner delivery chamber in fluid communication with an ejection port. The deliver chamber is formed within a tubular element axially slidable within a tubular guide. The tubular guide and the syringe outer barrel form an outer reservoir chamber. The outer reservoir chamber is sealed from the delivery chamber while the tubular element is in a first position within the guide. Upon withdrawal of the plunger, frictional contact imparted by the plunger seal causes the tubular element to slide away from sealing engagement with the barrel into a second position within the guide. In the second position of the tubular element, a fluid passageway is opened from the reservoir to the delivery chamber allowing fluid to be drawn into the delivery chamber. A porous seal between the plunger rod and barrel allows air into the reservoir during transfer of fluid to the delivery chamber.

Abstract: A coolant transfer machine for an automotive engine includes first and second fluid transfer systems. The first system, operated when the engine is not running, sequentially first removes at least a substantial portion of used coolant from the engine. The first system then collects in a used fluid container the used coolant as the used coolant is being removed and then replaces the removed used coolant with new coolant from a new fluid container. The second system, operated when the engine is running, simultaneously displaces at least a substantial portion of used coolant in the engine with new coolant from the new fluid container and collects the displaced used coolant in the used fluid container. A manually operable switch has a first position that enables operation of the first fluid transfer system and a second position that enables operation of the second fluid transfer system.
