Abstract
Abstract A rotary disk engine testing assembly comprising a rotatable platform adapted to receive a plurality of internal-combustion engines to be tested or run in, the rotatable platform being rotatably supported on a base support and driven in rotation by drive means. Each engine testing unit on the rotatable platform is provided with a friction brake for applying a load to the engine to be tested, means for clamping the engine, a starter motor and carburetor for such engine, means for connection of the carburetor to a fuel supply line on the rotatable platform, and exhaust gas discharge means.

Total Claims: 7
Claim 1
Independent Claim
242 words
A rotary disk engine testing assembly comprising a rotatable platform mounted on a rotary support block mounted on antifriction bearings; a base support carrying said antifriction bearings and drive means for rotation of said rotatable platform; a plurality of engine testing units spaced around the periphery of said peripheral platform; each of said engine testing units including a seat for an engine to be tested, at least one carburetor and a starter motor for starting said engine, a magnetic induction brake for subjecting said engine to a load, and a fan for conveying the exhaust gases from said engine through conduit means to a collecting column arranged in the center of said rotatable platform; a revolution indicator for indicating and recording the number of revolutions of the engines to be tested at the beginning and at the end of testing; a fuel tank in the form of an annular duct extending peripherally around and above said rotatable platform; a fuel recycling duct above said annular duct and connected thereto and to a fuel recycling pump; means for clamping the engine to be tested in each testing stand; at least two perpendicularly arranged air cylinders in each testing stand for moving the clamping means in two perpendicular directions toward and away from the engine to be tested, and an air pump connected through at least one air filter to an air collector and the air cylinders to feed compresses air to the latter.

Claim 3
Dependent Claim
38 words
A rotary disk engine testing assembly as claimed in claim 1, wherein said drive means for rotation of the rotatable platform comprises a motor with variator and reduction gear connected through a pinion to the rotary support block.
Claim 4
Dependent Claim
40 words
A rotary disk engine testing assembly as claimed in claim 2, wherein said variator is arranged for remote control by the operator to adapt the speed of rotation of the rotatable disk to the time required for testing the engines.
Claim 5
Dependent Claim
37 words
