Patent number: 6802210Abstract: A fuel pump module is formed in such a manner that a sensor unit having a semiconductor diaphragm is provided in a recess of a bracket having a flange portion holding a fuel pump through a high-pressure filter. The recess is closed by a sensor cap having a lead-in pipe to thereby form an tank internal-pressure sensor. While internal pressure of a fuel tank is led into the tank internal-pressure sensor through an internal pressure lead-in pipe, atmospheric pressure is led into the tank internal-pressure sensor through an external air intake hole provided in the lead-in pipe. Thus, internal pressure of the fuel tank is detected.Type: GrantFiled: April 10, 2003Date of Patent: October 12, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Tateki Mitani, Shigeki Kanamaru, Tetsushi Noda
