Summary:PURPOSE:To reduce the size of pump and to simplify the structure by employing an unimolf vibration chip for directly converting the electric energy to reciprocal motion or vibration in the pump mechanism thereby eliminating an intermediate transmission mechanism. CONSTITUTION:In a liquid feed pump employing an unimolf vibration chip 1 sticked of a thin metal plate 5 and a thin Piezo ceramic plate 2 for directly converting the electricity into vibration at the vibrating section for pressurizing the liquid, the thickness of said plate 2 is made to 0.4-0.7mm. and the outer diameter to 18-25mm. while the thickness of said plate 5 is made to 0.2-0.5mm. and the outer diameter to 25-30mm. for the delivery pressure of pump in the range of 0-0.20kg/cm . Consequently even upon application of A.C. allowable voltage of 50Hz or 60Hz, required amount of warming fuel can be delivered continuously without causing aging to enable elimination of an intermediate transmission mechanism resulting in reduction of entire size of pump and simplification of internal structure.
