  • the operation of the apparatus according to the invention is as follows. Examining firstly the method of identification of mechanical faults it will be noted that this operation requires two tests.
  • the first test consists of a measurement of the maximum pressure inside the explosion chambers of the cylinders. To do this the sparking plugs 46 are removed from their seats and the end connectors 16 are connected into said seats. Then the engine is made to move by means only of the starter motor. The pistons, during the compression stage, produce an increase in pressure downstream of the connector 9 by way of the flexible ducts 14. Thus the cylinder 23 is thrust to its limit and the spheres 25 are lifted so enabling the pressure gauges to register.
  • the sphere 18 of the end connectors 16 closes the axial bore 17, the closing of which, although not being perfectly tight, will be sufficient to maintain the maximum pressure value on the pressure gauges for a time sufficient to enable it to be read.
  • the second test is in practice a test of tightness of the explosion chambers, and is carried out in the following manner.
  • the shut-off valve 28 is opened, so enabling the receiver 7 to supply compressed air through the flexible duct to the distribution duct 8.
  • the piston in that explosion chamber for which the tightness test is to be carried out is put under compression by pushing the vehicle by hand, after having put it into top gear.
  • the compression caused by the piston thrusts the cylinder 23, the compressed air arriving at the distribution duct 8 through the duct 11, and opening the second non-return valve 13, will thus be able to enter the connector 9 and put the explosion chamber under pressure.
  • the faults are identified in positions corresponding to air leakage.
  • the third non-return valve 29 enables the pressure in the pressure gauge to be automatically discharged at the end of the operation.
  • An apparatus for the immediate identification of faults, particularly for explosion engines comprising a trolley stand and a compressed air receiver supported by saidtrolley stand; a valve body supported by said trolley stand; a distribution duct formed in said valve body and a flexible duct between said distribution duct and said compressed air receiver; a shut-off valve arranged in said flexible duct; a plurality of connectors formed in said valve body each being in the shape of a cylindrical cavity emerging at its lower end from said valve body and having a first passage bore near said lower end and a second passage bore near its upper end; a plurality of flexible ducts fixable to said lower ends of said connectors and terminating in end connectors threaded externally with the same pitch as the thread of the sparking plugs of an explosion engine; a plurality of pressure gauges each connected to the upper end of said cylindrical cavity of said connector; a plurality of first non-return valves each slidely housed in said cylindrical cavity of said connector and capable of opening when the pressure upstream of said lower end of said connector rises;
