Embodiment Construction

[0013] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0014] Referring to FIGS. 1 and 2, a crankcase pressure control valve according to the present invention includes a valve body 1 having a bowl shape, which is opened at an upper portion. The cover plate 3 closes the upper part of the valve body 1 . The diaphragm 5 is mounted on the lower part of the cover plate 3 . The intake hose joint 7 is arranged at the lower part of the valve body 1, protrudes downward from the valve body 1 and is connected to the intake hose. The throttling convex pipe 11 protrudes upwards from the inside of the valve body 1 and communicates with the intake hose joint 7 . The protruding end of the throttling convex tube 11 forms a throttling hole 9 opening toward the lower part of the diaphragm 5 . The bent joint 13 is provided on the side surface of the valve body 1 in such a manner as to extend upward at a certain angle...

Abstract

A crankcase pressure control valve with a bent nipple with a machined hole sealed later by a plug formed on a valve body. The crankcase pressure control valve has the bent nipple which makes linear access to the interior of the valve body difficult, thus allowing a bypass hole to be formed in the valve body through a relatively easy method using a slide core metal mold.

Description

technical field [0001] The present invention relates generally to the construction of crankcase pressure control valves with bent joints, and more particularly to the construction of a crankcase pressure control valve in which linearly entering Difficulty inside the valve body. Background technique [0002] The crankcase pressure control valve (CCPCV) is installed between the breather hose and the intake hose. When excessive intake negative pressure is generated, it plays a role in inhibiting the flow of blow-by gas through the breather hose to the intake hose. . [0003] The valve body of the CCPCV is respectively provided with joints connected to the ventilation hose and the intake hose. A diaphragm is provided within the valve body, supported by a spring, to control blow-by gas flowing between a fitting connected to the breather hose and a fitting connected to the intake hose. [0004] A throttle boss (throttle boss) is arranged around the joint connected with the inta...
