Title: Vibration damping arrangement using er fluid
Inventor: WATANABE ISAO
IPC: F16F9/18
Filed: 1995-12-08
Abstract: PURPOSE: To reduce the complexity of structure by providing an annular fluid feeding duct means in which electric flowable fluid is filled and an electrode means attached to an outside housing in order to increase the resistance of passing fluid. CONSTITUTION: The outside diameter of an inside cylindrical housing 2 is smaller than the inside diameter of an outside housing 25, and forms an annular fluid feeding duct 37. Also a piston 10 divides a chamber 11 into fluid chambers 38 and 39 which are interconnected with a feeding duct 37 by multiple openings 40 of a cylindrical body 3. When the piston 10 is moved inside the chamber 11, electric flowable(ER) fluid inside the chamber 11 passes through the openings 40 and flows along the feeding duct 37 between the fluid chambers 38 and 39. Because the fluid passes limited areas of the duct 37 adjacent to an electrode 52, the viscosity of the ER fluid varies depending on the amount of applied voltage and the width of a limited path, and has effect on damping characteristics.  Then an inside housing 2 and a piston rod 12 are installed on a vehicle, and absorb various forces affecting a shock absorber. Thus the complexity of the buffer can be reduced without sacrificing the buffering characteristics.

Title: Fuel injection valve
Inventor: SAKAKIDA AKIHIRO
IPC: F02M59/10
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To improve the fuel injection characteristics at the time of start in a so-called differential pressure type fuel injection valve which opens and closes a valve element by utilizing a differential pressure in the front and rear of the valve element. SOLUTION: When the operation of a fuel pump is started and a fuel pressure supplied to a fuel passage 5 increases at the time of engine start, a fuel pressure in a fuel reservoir 6 increases. On the other hand, a rise of fuel pressure in a differential pressure chamber 8 waits until fuel is introduced through a clearance between a needle valve 4 and a nozzle body 3, and a fuel pressure in the differential pressure chamber 8 is maintained at a low pressure during a predetermined period of time after engine start according to a conventional configuration. In this case, however, since a fuel pressure supplied from the fuel pump acts on a rear surface 10A of a piston member 10 for boosting pressure, the piston member 10 for booting pressure can move in the direction of middle and right in accordance with a rise of fuel pressure accompanying the start of operation of the fuel pump.  For this reason, it is possible to avoid improper opening of the needle valve 3 at the time of start as has been observed conventionally because a fuel pressure in the differential pressure chamber 8 can rise sufficiently at the time of engine start.
