Gas-oil separator for internal combustion engine of motor vehicle, has cap integrating conduit portion forming exhaust pipe for gas present in separator and membrane regulating exhaust of gas and pressure in separator

摘要

#CMT# #/CMT# The separator (1) has a lower opening (4) in fluid communication with an interior volume of a crankcase (2) of an engine. An upper opening (5) permits to supply the oil from the crankcase through the opening (4) and is closed by a cap (6). The cap integrates a conduit portion (7) by fluid communication with an internal volume (1`) of the separator and forms an exhaust pipe for gas in the separator, and a membrane (8) regulating the exhaust of the gas and pressure in the separator. The cap has a plastic main body (10) covered by a plastic cover (11). #CMT# : #/CMT# An independent claim is also included for a cap for a gas-oil separator. #CMT#USE : #/CMT# Used for being mounted at the proximity of a crankcase of an internal combustion engine of a motor vehicle for separating oil and gas surrounding a piston of the engine (claimed). #CMT#ADVANTAGE : #/CMT# The cap integrates the conduit portion forming exhaust pipe and the membrane regulating the exhaust of the gas and pressure in the separator, thus providing a single multifunctional sub-assembly realizing closing function, exhaust function or regulation function, and hence obtaining an operational gas-oil separator. The cap can be interchanged in a simple manner in case of failure of the membrane. The separator is realized in a reliable, simple and economic manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic and longitudinal vertical sectional view of a gas-oil separator. 1 : Gas-oil separator 1` : Internal volume 2 : Crankcase 4 : Lower opening 5 : Upper opening 6 : Cap 7 : Conduit portion 8 : Membrane 10 : Main body 11 : Cover.
