Title: Exhaust gas purifier for internal combustion engine
Inventor: ENDOU ISAMU
IPC: F02D35/00
Filed: 1979-10-04
Abstract: PURPOSE: To control properly constant speed travelling time in acceleration by a single negative pressure control which is interposed on the way of negative pressure paths to a vacuum angle advancing device and EGR valve for a distributor and controlled by negative pressure in an exhaust system.  
     CONSTITUTION: When a throttle valve 3 is opened to a predetermined opening to be located somewhat upstream of a negative pressure port 4, intake negative pressure acts on a vacuum angle advancing device 7 for a distributor 6 to advance angle for ignition period. When the throttle valve 3 is further opened to be located somewhat upstream of a negative pressure port 15, the negative pressure acts on a negative pressure chamber 13 in an EGR valve 12 to open the valve 12 and circulate exhaust gas. On the other hand, when acceleration is carried out during said action, back pressure in an exhaust manihold 18 is enhanced to be supplied through a path 17 to a back pressure chamber 22 in a negative pressure control 9. Thus, a valve 33 is opened through a diaphragm 21 to communicate a negative pressure chamber 30 to an atmosphere chamber 23 for reducing an amount of angle advancement. Also, then, the circulation of exhaust gas is more positively carried out.

Abstract: PURPOSE:To inspect the leakage of an empty vessel utilizing the releasing state of the vacuum attracted vessel, by a method wherein, after the opening of the vessel is closed off and air is exhausted from the inside, said condition is held for a given period of time. CONSTITUTION:A block body 26, positioned facing to an opening, is inserted into a vessel 10, a packing member 28 is brought into contact with a rim 18 to seal the opening, and simultaneously, a plate 42 is brought into contact with a bottom plate 14 to pressurized and compress a spring 40.

As a result, a suction force surpasses the restoring force of the spring 40, which results in bringing the vessel into a state to press it against a base 24. It is then left standing for a given period of time, and based on the given period of time, if the vessel drops from a retainer by the restoring force of the spring 40 before said period of time has elapsed, the vessel is deciced to be poor, and conversely, if it drops after the period of time has elapsed, it is decided to be an accepted one.

In general H>>1 exists, and even when the H is fluctuated more or less, (H-1)/H is not almost changed but nearly the unity. Since relation of RD<<RA exists, the cause to distortion is expressed in equation II as K, and the distortion of the output is decreased to zero by deciding the resistor RD so as to form K=O.
