Abstract (en)

[origin: EP0874141A1] A throttle limits flow through the pipe, and is formed by a plastic component with inlet union for the pipe and an outlet. A metal bush fixed in a drilling through the component has a screw by which the component is secured to the cylinder-head. This throttle (12) forms part of the pipe (7), and is situated at the heat-conductive bush (11). The pipe can intersect the drilling (9) and bush, the throttle being incorporated in the latter. It can form an extension of the inlet union, leading into an annular chamber (13) between bush and screw (15). The radial outlet drilling (16) to the engine intake (6) and which passes through the bush is of larger diameter (16). Where the engine has four or more cylinders, the inlet union and throttle can be situated between the intake pipes to two adjacent central cylinders, while the throttle is at the highest geodetic point of the crankcase vent system.
