Title: Quantitative differential pressure pump using compressed gas
Inventor: HAMAGUCHI SHIGEO
IPC: F04B13/00
Filed: 2002-09-26
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems that an electric motor is connected, heat is easily generated due to mechanical friction, and electric control and the like is required to complicate a structure, in a conventional pump for drawing out liquid.  <P>SOLUTION: The quantitative differential pressure pump using compressed gas is installed in liquid, and provided with a container called as an airtight chamber attached with an opening/closing valve. A deformed differential pressure pipe is attached to a linear discharge pipe. A pneumatic pressure pipe is connected to the airtight chamber. When compressed gas is sent, liquid in the airtight chamber is pressed out from the discharge pipe by quantitative amount. When the gas is released from the discharge pipe, inner pressure is lowered. The valve in the airtight chamber is opened, and the fluid is made to flow in again, so that the liquid of the quantitative amount is drawn out by the compressed gas. The quantitative differential pressure pump is composed of the airtight chamber, the valve, and the pipe.  <P>COPYRIGHT: (C)2004,JPO
