Title: Fuel injection valve for diesel engine
Inventor: TERASAWA MICHITAKA
IPC: F02M61/10
Filed: 1989-06-26
Abstract: PURPOSE:To simultaneously realize the reduction of the initial injection rate and the sharp cut at the end of injection by installing a needle valve, pressure pin, nozzle spring, and a free weight and contact-engagement-holding the pressure pin and the free weight in free contact. CONSTITUTION:When a needle valve 3 which lifts against a needle spring is opening-operated, a pressure pin 4 which rises together with the needle valve 3 pushes up a free weight 9 from below through contact. On the contrary, when the needle valve 3 is cloing-operated for return, the pressing force of a nozzle spring 6 acts onto the pressure pin 4 and the needle valve 3, and the free weight 9 does not act. Since the weight of the free weight 9 acts as the weight of a movable part, when the valve is opened, the following performance is deteriorated, and the initial injection rate is reduced. Further, when the valve is closed, the weight of ths free weight 9 does not act, and the following performance is improved, and the fuel exhaustion characteristic can be improved, fuel injection quantity can be stabilized.

Title: Electromagnetic proportional relief valve
Inventor: MASUDA KENJI
IPC: F16K31/06
Filed: 1978-12-28
Abstract: PURPOSE: To make a response satisfactory to a relief flow by displacing poppet- shaped valve body and valve seat into a direction mutually opposed to each other at the time of variation of relief flow.  
     CONSTITUTION: If an electric current of a prearranged value is applied to proportional electromagnet 2, the solenoid suction force acts on armature 17, and poppet 19 forcefully pushes movable valve seat 6 to the left, compressing spring 9. Then poppet 19 stops where solenoid suction force and a force generated on spring 9 are balanced. The pressure of fluid circuit connected to the primary port 11 acts on the edge surface of poppet 19. If this action reached a value of overpowering the solenoid suction force, poppet 19 is displaced to the right and the movable valve seat 6 to the left, relieving the primary port 11's fluid into tank port 15 by way of tank line 14. In this way, the pressure of the primary port 11 is controlled so that it may have a value corresponding to the solenoid suction force.

As the result of it, at the time of normal air-conditioning, the temperature of the side walls and interior equipment in a room can be approached to a preset value, and a comfortable space can be spread over the whole of the room, in using radiation like arrow marks, each of which is shown with a broken line. When air-conditioning operation begins to be started, or at the time of cooling immediately after the person enters the room, air-flow-shifting louvers 3 are variably controlled one by one so that the direction of air-flow blown directly faces the human body, while being operated together with indoor conditions estimated and detected by a timer or a human body-detecting sensor, and such is also effective for the comfortable space.
