Rocker chamber cover assembly system with respirator

Abstract

The invention discloses a rocker chamber cover assembly system with a respirator, which is characterized in that a rocker chamber cover body is provided with a respirator working cavity in which a labyrinth space is arranged; a cover board of the respirator working cavity is fixed and sealed on the rocker chamber cover body through the sealing surface of the respirator working cavity so that an independent sealed respirator is formed in the rocker chamber cover body. The rocker chamber cover body is provided with a respirator outlet used for communicating a crankcase with the air. The rocker chamber cover assembly system with the respirator is arranged on an engine through bolts on the rocker chamber cover body. The invention has simple and reasonable design structure, and can effectively save the surrounding space of the engine. The rocker chamber cover assembly system with the respirator has double functions of the sealed rocker working cavity of the rocker chamber cover as well as the functions of separating engine oil from gas and communicating the crankcase with the air. The invention is also beneficial to designs of other engine auxiliary devices.

Description

Technical field [0001] The present invention is an engine parts, which involves a system of ventilation of rocker house cover and crankshaft box. Background technique [0002] With the popularization of car familyization, people's requirements for car comfort are also getting higher and higher, such as high -power air conditioning, steering assistance, brake assistance, electronic flameout, exhaust braking and other auxiliary functions.The transmission support mechanisms of these auxiliary devices are arranged on the engine, so the shape space of the engine is becoming more and more tense. Therefore, it is often forced to abandon some functions and weaken the comfort of the engine and the vehicle.Therefore, the reasonable setting of the engine space has become one of the design principles of the engine. [0003] The rocker room cover and the respiratory device are indispensable components of the engine work. The function of the rocker bundle hood is to close the work space of the...

AI Technical Summary

Problems solved by technology

At present, the design of the respirator and the rocker chamber cover is often carried out separately, and the respirator body, respirator inlet, respirator outlet, respirator oil return port and corresponding connecting pipelines need to be designed separately, and the shape and structure are complicated. It takes up a lot of space, and the adjacent and similar parts are difficult to arrange, have complex shapes or are forced to give up
