Definitions

the piston is connected to a drive kinematism, typically of the connecting rod-crank type, which allows it to slide between an upper dead centre position and a lower dead centre position.
the outer surface of the flexible membrane 150 i.e. the one facing the drive shaft 105, may be placed in contact with and fixed to the thrust surface (or top) of the piston 115, for example by means of a screw 185 and a fixing washer 190 placed in middle position both with respect to the flexible membrane 150 and with respect to the piston 115.
the sealing ring 200 when the piston 115 is in the lower dead centre position, the sealing ring 200 is positioned below or at least at the aforesaid primary passages 205, thus allowing the latter to create a direct communication between the intermediate chamber 195 and the internal volume 145 of the casing 140. In this manner, when the internal volume 145 of the casing 140 is filled with the lubricating oil, the latter may also penetrate and completely fill the intermediate chamber 195, thus creating a lubricating oil cushion which concurs to transmitting the thrust exerted by the piston 115 during the compression stroke, to the flexible membrane 150.
each secondary passage 210 it is preferable for the passing through cross-section of each secondary passage 210 to have an extension which is less than 0.2 mm 2 , and more preferably less than 0.05 mm 2 .
