NOZZLE TESTING APPARATUS Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: apparatus has hand-held pump with fuel tank and plunger pair, which are interconnected and mounted on casing. Plunger pair, suction and delivery valves are arranged in mutually perpendicular axes one with respect to the other. Fuel cut off unit is arranged in axially aligned position with suction unit. Fuel cut off unit is made in the form of member movable in horizontal plane and is mounted in front of suction valve. Injection chamber and suction chamber are of equal volumes, are mounted parallel one with respect to another and relatively offset in vertical plane. EFFECT: increased efficiency and quality of nozzle testing by increased fuel volume for pump working stroke and reduced time intervals. 22 cl, 3 dwg _
