Abstract

The invention discloses a device for suction and decantation of a crankcase gas and associated installation. The subject of the invention is a crankcase gas suction and decanting device (1) comprisingat least a combustion gas and engine oil, The suction and decanting device (1) comprising a crankcase gas collecting cylinder (2) comprising a cylinder inlet (2a) shaped to supply a crankcase gas anda cylinder outlet (2b) arranged tangentially to the cylinder (2); a first conical portion (3) comprising a first end (3a) and a second end (3b), the first end (3a) being arranged at the cylinder outlet (2b), the first conical portion (3) being convergent from its first end (3a) to its second end (3b), characterized in that the suction and decanting device (1) further comprises a second conical portion (6) having a first end (6a) and a second end (6b), the first end (6a) of the second conical portion (6) being positioned opposite the second end (3b) of the first conical portion (3), the secondconical portion (6) being divergent from its first end (6a) towards its second end (6b).

Description

technical field [0001] The present invention relates to the technical field of motor crankcase gas recovery and treatment systems having the introduction of air into the motor crankcase also known as "positive crankcase ventilation" and its acronym is a PCV. The invention preferably applies to vehicles equipped with such a crankcase gas recovery system that introduces air into the motor crankcase. Background technique [0002] In this application, the term "crankcase gases" refers to motor combustion gases mixed with small amounts of motor oil particles released from the motor pistons and cylinders. In operation, this combustion gas mixes with oil particles in the hermetically sealed lower motor. When there is too much crankcase gas formed, the pressure of the lower motor will rise which can cause operational problems of the motor, leaks etc. which can lead to motor failure. The term "lower motor" refers to the lower part of the motor, typically including the crankshaft, ...
