Title: Oil level checking stick - produces low level output signal when tube draws in air instead of oil
Inventor: PREIKSCHAT REINHOLD
IPC: F01M11/12
Filed: 1979-04-28
Abstract: A dipstick for measuring the oil content of engines, gear-boxes, machines and tanks produces a continuous signal if the oil falls below a min. level. This constitutes automation of the oil level check which is often neglected because of teh tediousness of removing a conventional dipstick, cleaning it, reinserting it, and removing it again so as to read off the level. The dip-stick, which can also be used in the conventional manner, consists of a suction tube with a ventilation nozzle, an electrical shut-off valve, and two under pressure switches controlled by relays to produce the continuous signal for a too-low oil lvel. The switching of one under pressure valve normally precedes that of the other. If the level is too low the pipe draws in air instead of oil and the switching sequence is disrupted enabling low level detection.
