A fuel supply apparatus according to the present invention includes vapor production determining means for determining whether or not the vapor of the fuel is producible, and control means (ECU) for operating a passage resistance adjusting means of a pressure adjusting mechanism to cause increase of the pressure of the fuel supplied to an injector insomuch as the production of the vapor is inhibited when the vapor production determining means has determined a vapor producible condition.

Fuel supply apparatuses

A vibration type driving device in which a piezoelectric element is interposed between a pair of blocks connected to each other by a rod, a part of the surface of the piezoelectric element being covered with an electrode. Application of high frequency voltage to the electrode causes resonance of vertical vibrations and bending vibrations, which is effective to generate elliptical movement of the end surface of the block. The electrode is divided into three or more sections, preferably into four sections. A change-over switch is provided for selecting the electrode sections to be energized in accordance with the direction of the driving force. This permits linear movement of an article in a desired direction.
