Title:
METHOD OF FILLING OIL AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JPH01240497
Kind Code:
A
Abstract:

PURPOSE: To enable an accurate and rapid filling of oil, by firstly filling oil at a high speed below an aimed level and then continuing oil filling at a decreased velocity to allow a level of a gauge to effect an accurate level measurement so that occurrence of wavy fuel surface is prevented.

CONSTITUTION: A push button 19 is depressed to the ON position such that feeding of oil through an oil-feeding pipe 7 is initiated. Simultaneously, a pressure-control valve 16 is moved to the high-pressure side such that a large open degree of a flow control valve 3 is maintained by introducing a high pressure air into an operating chamber 8 and oil is charged at a high speed. When a transmission case is filled with oil up 'H' level below an aimed oil level, the pressure-control valve 16 is moved to the low pressure side in response to a measuring signal generated from a flow meter 15 so that the air pressure exerted to the operating chamber 8 is decreased so as to maintain the lower open degree of the flow control valve 3. When the aimed oil level 'H' is achieved, the pressure control valve 16 is exposed to an atmosphere to close the flow control valve 3. Accordingly, filling of oil through a charging head 2 is surely terminated at the aimed oil level 'H'.
