Title: Intake air flow control device for internal combustion engine
Inventor: DEGUCHI YOSHITAKA
IPC: F02M69/32
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain intake air flow with high accuracy according to a load of a fluid pump driven by an engine. SOLUTION: In the steady state, a hydraulic pressure of a pressure chamber 12 and a hydraulic pressure of a pressure chamber 14 are different from a discharge pressure of a hydraulic pump, and forces pressing a partition member 15 from right and left are different from each other. Therefore, when the discharge pressure of the hydraulic pump is large, the partition member 15 is displaced against a spring 19, and the opening degree of a valve element 18A is continuously controlled according to a load of the hydraulic pump. Also, when the discharge pressure of the hydraulic pump is changed, the hydraulic pressure of the pressure chamber 12 is changed according to this, but the hydraulic pressure of the pressure chamber 14 is changed with a delay due to an influence of an orifice 13A.  Thus, as a large difference in pressing forces is generated at the partition body 15 in the transient manner, the valve element 18A is moved differentially with good responsiveness to the load change of the hydraulic pump. Thus, an engine intake air flow according to the load of a fluid pump can be obtained with high accuracy both in the steady and the transient states.

Abstract: PURPOSE:To equalize the respective operational states on discharge side and on suction side and consequently reduce the vibration noise of a fan by a structure wherein heat pipes are provided concentric with fan blades in a space between fan casings and the fan blades contained in the fan casings. CONSTITUTION:When the air in the interior 31 of a room passes through the discharge side of heat pipes 24 and simultaneously the air in the exterior 32 of the room passes through the suction side of the heat pipes 24, the air discharged from the interior 31 of the room and the air sucked from the exterior 32 of the room are heat-exchanged with each other so aa to recover the heat of the discharged air to the air sucked, resulting in lightening the air conditioning load and at the same time reducing the number of the constitutional parts and simplifying the structure of a heat exchange device. In addition, because the heat pipes 24, which cause the resistance of air flow, are respectively provided between blades 21 and fan casings 22a and 22b on both the discharge and suction sides, the difference between the operating states of the fan at the discharge side and the suction side is eliminated, resulting in reducing the vibration noise of a fan 25 containing the heat pipes therein.

Filed: 1980-05-27
Abstract: PURPOSE:To enhance optical transmissivity by controlling a metal ring having an oxide film only on its inner surface and a glass plate whose volume is the same as that of the inside of said metal ring thereon, heating the device, and forming smooth free surfaces on the top and bottom of said glass. CONSTITUTION:The Fe ring 10 and the glass disk 11 are coupled in a hole 16 of a jig. The glass disk is melted by heating, and the melted glass is remained on the top of the ring 10 which is not initimate, due to the viscosity and the surface tension of the glass. The melted glass 17 is flowed into an intimate inner diameter part 14 wherein the oxide film 13 is formed and contacted to the oxide film in the inner diameter part. The top surface of the glass becomes the free surface. While the melted glass 17 does not become intimate with the bottom surface of the Fe ring, and since the escape hole 16 is provided at the bottom of the inner diameter part 14, the bottom part of the melted glass 17 forms the free surface between the lower edge of the oxide film 13 due to the surface tension and viscosity. If the inner diameter D2 is small, the concave shape is formed, while if D2 is large, the convex shape which is bulged downward to the hole 16 is formed. In this constitution, the optical transmissivity can be increased and the manufacturing thereof is facilitated.
