Title:
デュアルポンピング流体ポンプ
Document Type and Number:
Japanese Patent JP6759334
Kind Code:
B2
Abstract:
A dual pumping fluid pump which significantly reduces vibration and noise generation. When a cam installed on a rotating shaft of a single electric motor is rotated, a pair of first and second diaphragms installed in connection to an eccentric shaft portion formed on both the left and right sides of the cam alternatingly rise and descend in opposite directions and cause first and second intake check valves and first and second discharge check valves provided on a fluid passage box integrally and connectedly installed on the top surface of a pump housing to open or close first and second intake holes and first and second discharge holes to admit fluid through a fluid inlet and simultaneously discharge fluid through a fluid outlet, so that the simultaneous effects of the intake pressure and discharge pressure of fluid causes pressure balancing to occur.
