Abstract
PURPOSE: To prevent oil from remaining unfavorably in a vacuum pump during high vacuum for avoiding seizure or the like of the pump by connecting a piping capable of introducing air corresponding to the degree of vacuum in the pump to the discharge side of the pump in a tank truck for collecting night soil.
CONSTITUTION: A tank track used for collecting night soil sucks air in a tank 1 through a manhole 2, air cleaner 4, suction/exhaust change-over cock 3 and check valve 6 and then discharges the air to the atmosphere through a combined oil tank and separator 7 and port 3d of the suction/exhaust change-over cock 3 by an engine driven vacuum pump 5'. In this case, the vacuum pump 5' is provided on the discharge port 5b side with an air introducing port 18 connected to said separator 7 through a pipe path 19. Thus, while vanes 17, 17 rotate from between A-B to between D-C during high vacuum in the tank 1, they suck air in the separator 7 through the pipe path 19 so that they overcome problems of the pump 5' filled with oil from the separator 7.
