Title: Intake device of engine
Inventor: KURIO NORIYUKI
IPC: F02B27/02
Filed: 1985-03-29
Abstract: PURPOSE:To eliminate a time delay of intake air when an engine is accelerated, by providing an extensible and contractible chamber member in the side part of an intake passage in the upstream of a throttle valve and switching the negative pressure or the atmospheric pressure to be introduced into a housing chamber of the chamber member in accordance with an operative condition of the engine. CONSTITUTION:An engine provides an extensible and contractible chamber member 8 through a branch pipe 7 in the side part of an intake passage 2 in the upstream of a throttle valve 6a of a carburetor 6. A housing chamber 9 of the chamber member 8 selectively communicates with an atmospheric pressure pipe line 10 and an intake negative pressure introducing pipe line 11 through a selector valve 13. When the engine is in normal operation, the selector valve 13, connecting the negative pressure pipe line 11 with a pipe 12, introduces a negative pressure into the housing chamber 9. In this way, the extensible and contractible chamber member 8, introducing inside the negative pressure, extends to store air in the inside. While the selector valve 13, connecting the atmospheric pressure pipe line 10 with the pipe 12 and generating the atmospheric pressure in the housing chamber 9 when the engine is accelerated, compresses the chamber member 8, and the engine, jetting the air inside the chamber member into intake, improves acceleration performance.

Filed: 1980-05-23
Abstract: PURPOSE: To manufacture a fan-shaped strip in a high yield through a single rolling pass, by rolling a straight strip with a draft percentage gradually increased from one edge to another edge of the strip.  
     CONSTITUTION: A straight strip 1 with breadth W 0 , total length L 0  and thickness T 0  is rolled with a draft percentage increased from its one edge to another edge. Hereupon, the strip 1 is rolled by two rolling rolls 2, 3 whose axis lines make an angle α. The left and right axial distances of two rolls 2, 3 are adjusted by operating an adjuster such as bolt, wedge,etc., in order to adjust the angle α made by roll axes of the rolls 2, 3 and to adjust the left and right thicknesses t 0 , t 1  of the rolled strip. A fan-shaped strip 1' obtained by this rolling pass can be formed from a straight strip 1 as the blank material so that the yield is improved and the material is saved, which reduces the material cost; and besides, the fan-shaped strip 1' can be obtained by a single rolling pass so that the working man-hour is reduced.
