Title:
PRESSURE TESTING PUMP
Document Type and Number:
Japanese Patent JP3387960
Kind Code:
B2
Abstract:
PURPOSE: To reduce operation power and improve pump capability by providing at least a container for storing a fluid and a piston-cylinder type pump pivotably mounted thereto, and arranging means for actuating the pump by swinging a lever or the like.
CONSTITUTION: A pump 10 for sending a fluid under pressure into a fluid system for testing leakage or the like comprises a container 12 for storing a sent-out fluid, and a piston-cylinder type pump 15 actuated by a lever 16. The lever 16 swings about a lever pivot axis 138. Furthermore, the piston-cylinder type pump 14 is mounted to the container 12 in the manner that it can pivot about a pivoting axis 68. In addition, an end of a piston rod 56 is coupled to the lever 16 in the manner that it can pivot about a pivot axis 146. Then, a discharge capacity becomes larger when lever 16 is swung greatly. On the other hand, the discharge capacity becomes smaller while a discharge pressure becomes higher when the lever 16 is swung slightly near a terminal of a discharge stroke.
