Engine oil level measurement device for sound proof encapsulated internal combustion engines
First Claim
1. A device for the measurement of the engine oil level in sound proof encapsulated internal combustion engines by means of an oil dipstick, said device comprising an oil dipstick, and a dipstick guide tube comprising two coaxially and successively arranged guide tube parts, the inner of said two guide tube parts adapted to be secured to the engine and the outer guide tube part adapted to penetrate the encapsulation and be fixed thereto, said two guide tube parts being elastically and leakproof connected with each other by sealing means, and the inner guide tube part of the guide tube having a smaller diameter than the outer guide tube part, said inner guide tube part enlarging in diameter in the range of the connection of both guide tube parts to approximately the diameter of the outer guide tube part, said enlarged diameter of the inner guide tube forming a seat for a detent on the oil dipstick.
