Title: Hydraulic cylinder
Inventor: HORIGUCHI AKIRA
IPC: F15B15/14
Filed: 1989-01-11
Abstract: PURPOSE:To aim at perfect air extraction of the lower side hydraulic chamber by providing an air extraction valve at a piston which divides the lower side hydraulic chamber from the upper side hydraulic chamber and further providing a check valve to prevent working fluid from flowing from the upper side hydraulic chamber to the lower side hydraulic chamber. CONSTITUTION:In order to extract air in the lower side hydraulic chamber 3, a directional control valve 9 is put at the position i. Working fluid is led to a hydraulic chamber 3 from a hydraulic source 7 through the directional control valve 9 and check throttling valves 10 and 11. As the working fluid is further led into the hydraulic chamber 3, air collected in the hydraulic chamber 3 passes through a movable restrictor 1-1 of an air extraction valve and flows to the upper side hydraulic chamber 4 through a check valve 2-1. As an air intake of the air extraction valve is positioned at the top part of the hydraulic chamber 3, air in the hydraulic chamber 3 is perfectly extracted. Also, when air flows through the restrictor 1-1, differential pressure is generated in the direction to close the restrictor 1-1, but if strength of a spring 1-2 is selected at the level that the restrictor 1-1 is not closed by the pressure of air, air in the hydraulic chamber 3 can be led to the hydraulic chamber 4.

Title: Fuel injection control device for two-cycle engine
Inventor: YAMANAKA AKIHIRO
IPC: F02D41/34
Filed: 1993-01-11
Abstract: PURPOSE:To ensure excellent startability through prevention of wetting of an ignition plug by injecting fuel in such a way that the fuel injection is divided into two times until the number of revolutions of an engine is increased to the predetermined number of revolutions atler start of cranking. CONSTITUTION:A recessed groove 15 extending from a position below an ignition plug 10 to a position below the tip part of a fuel injection valve 14a is formed in the top surface of a piston 2. During a period in which warming-up operation is carried out after the start of an engine, fuel is injected from a fuel injection valve 14a toward the recessed groove 15 at the terminal phase of a compression stroke, and fuel air mixture G is generated in a limited region around an ignition plug 10. In this case, first fuel injection is effected at the terminal phase of a scavenging stroke during a period in which the number of revolutions of an engine is increased to a specified value after the starting of cranking, and then second fuel injection is executed at the terminal phase of a compression stroke. Thus, an amount of fuel injected is reduced and an amount of fuel liquid drops rebounding on the bottom wall surface of the recessed groove 15 is also reduced, whereby the ignition plug 10 is prevented from being wetted so much and excellent ignition can be carried out. Further, after the number of revolutions of an engine exceeds the specified number of revolutions, fuel is injected only one time at the terminal phase of a compression stroke.
