Title: Intake device of internal combustion engine
Inventor: MORITA HIDEO
IPC: F02D33/00
Filed: 1979-06-14
Abstract: PURPOSE: In an intake device which has an air introducing device workable in deceleration provided in, to make it possible to compensate the number of idle revolution with a simple constitution when using an auxiliary machine by providing a mechanism which can introduce air compensating the idle revolution even at a start of the auxiliary machine to the downstream of a throttle valve.  
     CONSTITUTION: An air passage 11 is provided bypassing a throttle valve of an intake passage, and in the passage 11 is mounted a control valve 12. This control valve 12 presses a valve body 18 down through a diaphragm 22 and a rod 29 by a rapid increase of a negative pressure introduced into a negative pressure chamber 23 from a negative pressure passage 28 communicating to the downstream of the throttle valve, in a rapid deceleration at which the valve is closed rapidly, and opens. Then the bypass passage 11 is released to introduce a fairly large quantity of air to the intake passage 2. When a switch 46 is on following a start of an auxiliary machine, a plunger 45 of an electromagnetic change valve 44 communicates a negative pressure passage 40 to an intake passage in the downstream of the throttle valve to introduce negative pressure to a negative pressure chamber 37, by which a diaphragm 36 is moved downward to open the valve body 18 in the same manner as above.

Abstract: PURPOSE:To reduce the number of parts, to better assembly workability and to improve reliability by forming a bearing holder and a stator core from a core member formed into an integral body through a sintered powder metallurgy and provided with a bearing fitting part and by impregnating said core member with a lubricating oil. CONSTITUTION:A core member 22 is provided with a shape, where a bearing holder and a stator core are molded into an integral body by a sintered powder metallurgy, while forming a bearing fitting part 23, said bearing holder part 24 and stator core part 25 so that a work for fitting said bearing holder with said stator core becomes useless to improve workability. Further, because the stator core part 25 of said core member 22 is also impregnated with a lubricating oil, it is possible to increase the oil-holding quantity of an apparatus and to lengthen the life thereof. Thus, because it is unnecessary to provide the bearing holder and stator core separately and to fit them together, the number of parts decreases and the workability becomes better.

Abstract: PURPOSE:To perform mixing and separation of a fluid highly accurately, by  flowing the heating fluid through the inside of walls of a cylindrical body. CONSTITUTION:A fluid to be separated flows into a cylindrical body 7 from a flow-in port 17 and passes through a fine slit-shaped path 5 of a separating element 6, and ony the separated dispersing medium passes through the inside of cylindrical body 7 and attains to a flluid flow-out port 11. Further, when the heating fluid injected from a heating fluid inlet port 8a flows meanderingly through the inside of the walls of the body 7 and flows out from a heating fluid flow-out port 8b, the body 7 and filament-shaped materials 4' are heated to high temperature. Next, when air pressure or hydraulic pressure is added to a pressurizing port 16, a piston 15 descends rapidly in response to the pressure. Consequently, a part of the fluid in the element 6 flows reversely toward the outside because the pressure in the element 6 increases rapidly and becomes higher than that of the outside, thus washing of the element 6 is performed.
