IPC: B60G17/015
Filed: 1991-11-20
Abstract: PURPOSE:To automatically adjust damping force of a base valve in response to damping force of the damping force generating mechanism of a piston. CONSTITUTION:A main oil-liquid passage 9 on the side of contraction that communicates a cylinder lower chamber 2b and a reservoir chamber 6a and a bypass passage 10 are provided in the valve main body 8 of a base valve mechanism 7, and a spool valve mechanism 14 that opens/closes the bypass passage 10 is also provided. Oil-liquid in the cylinder lower chamber 2b is pressurized by sliding of a piston fitted to a cylinder 2, and that pressure is transmitted to a spool 16 by a pressure inlet hole 17. Since the spool 16 becomes to locate at a valve opening position as shown in the drawing by a spring 19 to open the bypass passage 10 when the pressure in the cylinder lower chamber 2b is low, damping force of the base valve is reduced. When the pressure of the cylinder lower chamber 26 is not less than that specified, since the spool 16 moves by that pressure withstanding energized force of the spring 19 and the bypass passage 10 is closed, damping force of the base valve is raised by the main oil-liquid passage 9 and a damping force generating mechanism 12.

Title: Liquid fuel combustion device
Inventor: HARA HISAO
IPC: F23N5/00
Filed: 1990-11-30
Abstract: PURPOSE:To enable combustion having a predetermined heating calorie to be performed rapidly by a method wherein it is judged whether a required amount of combustion is rapidly changed from a value just before its changing state to its lower value and when it is judged as a rapid changing, the required amount of combustion is changed to a smaller value for a short period of time. CONSTITUTION:When a degree of opening of a hot water feeding plug is narrowed during combustion, a required amount of combustion 1 is rapidly changed to its lower degree side from a point (a) to a point (b). At this time, a judging means 4 detects this rapid changing and a temporary changing means 5 is operated, so that a required amount of combustion is changed from the point (b) to the lower point (c) and this state is continued for a short period of time (t). Since a fuel oil feeding amount of a pump 6 is remarkably low during this short period of time, non-gasified fuel oil within a gasification chamber 10 is rapidly reduced. Then, at the time when the value returns to the point (d), an amount of non-gasified fuel oil is present at a normal amount in a required softening amount and subsequently a burner 12 performs an ignition at a predetermined heating calorie, resulting in that hot water of high temperature is not produced and the hot water can be used safely.
