Abstract
The present invention relates to a method of providing nearly constant pressure during operation of a device incorporating a pressurized container and more particularly pre-ignition lubrication mechanisms for internal combustion engines, pressurized pre-combustion oiling mechanism for use with internal combustion engines, pressurized water or other fluid tanks, and pressurized fluid and other pressurized material dispensers. The present invention provides an accumulator tank containing either air or an easily condensed gas. The pressurized oil causes the air or gas in the bag to become compressed, causing a decrease in occupied volume in proportion to the pressure induced by the oil to allow the oil to occupy a suitable portion of the tank. In the preferred embodiment of the invention, the pressurized oil would cause the easily condensed gas to undergo a phase change and liquify. Conventional valving known in the state of the art is provided to allow the accumulated pressurized oil to be used prior to a subsequent engine startup, and conventional electronic control systems are provided to engage and disengage the aforementioned valves for a proper pre-ignition lubrication sequence. The present invention also provides a means of enhancing the volume of oil delivered by the accumulator.
