  • My invention refers to the testingof internal combustion motors and moreespecially to a chamber serving for the testing of motors for-aviation purposes and being adapted to be closed air-tightly so that a reduced pressure can be produced in its interior.
  • My invention therefore consists in a testing chamber provided with a high power exhaust fan for removing the exhaust gases.
  • the suction pipe is further provided with openings serving for effecting a connection with the interior of the chamber and thereby providing that the pressure prevailing at the exhaust valve and the other parts as well as in the interior of the chamber is the same.
  • the exhaust fan can carry away more than the maximum of exhaust gases available, every danger of the Said gases accumulating or striking back into the interior of the chamber is avoided.
  • suction pipe communicating with the interior of the chamber prevent the exhaust piping to be evacuated unduly to a greater extent than the interior of the chamber;
  • the exhaust box fresh cooling air may easily be sucked infor: the exhaust gases which are quickly passingthrough it.
  • a testing chamber constructed in accordance with my present invention is illustrated by way of example, the diagram showing a horizontal section of a simple evacuation chamber with a motor arranged therein.
  • A is the chamber closed on all sides andhaving walls made of reinforced concrete with a double door a arranged therein.
  • B is the motor whose cylinders are connected to a common exhaust box C.
  • the exhaust box whose outlet portion is reduced after the manner of a nozzle, is surrounded by atubular acket D having one end communicating freely with the chamber A, while its other end is connected with the suction head a of the fan E.
  • the suction head 6 communicates directly with the interior of the chamber by means of inlet openings 6 which are preferably provided with flap valves adapted to open as soon as the pressure within the head 6 has fallen to a small predetermined extent below the pressure within the chamber.
  • a pressure pipe 6 of the fan E leads into the atmosphere.
  • the desired reduced pressure is maintained within the chamber by means of a reducing valve F provided therein and which may be adjusted to any desired re duction, the suction pipe of said valve being traversed by fresh air whenever the reduction of air within the chamber is likely to exceed the predetermined value.
  • a closed chamber designed to take up the motor to be tested a high power exhausting device in said chamber having openings in the exhaust piping for establishing a communication between the interior of said piping and the interior of said chamber and means for establishing a connection between the exhaust side of said motor and the intake of said exhausting device.
  • a closed chamber designed to take up the motor to be tested, a high power er hausting device in said chamber having openings in the exhaust piping for establishing a communication between the interior of said piping and the interior of said chamber and means for establishing a connection between the exhaust side of said motor and the intake of said exhausting device, and a reducing valve, communicating with the outer air.
