Filed: 2003-10-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid jet apparatus which can strengthen a negative-pressure suction force to be imparted to a capping means in a short period of time.  <P>SOLUTION: This liquid jet apparatus is equipped with: the capping means 13 which seals a liquid jet head 8 and which sucks in a liquid from a nozzle opening 8b by receiving negative pressure from a negative-pressure generating means 16; a negative-pressure control valve 18 which is interposed between the capping means 13 and the means 16; and a valve control means 28 for controlling the opening/closing of the valve 18. A negative-pressure accumulation part 30, whose capacity can be varied and to which an urging force in the direction of an increase in its capacity can be imparted, is arranged between the valve 18 and the means 16. Thus, the negative pressure is accumulated in the accumulation part 30, and concurrently with that, the capacity of the accumulation part 30 is also reduced, so that the urging force can be generated in the accumulation part 30. The urging force is added concurrently with the opening of the valve 18, so that the negative pressure of the capping means 13 can be rapidly increased.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: F02B29/08
Filed: 2003-11-05
Abstract: <P>PROBLEM TO BE SOLVED: To reinforce gas fluidity such as swirl and tumble to stabilize combustion when an internal combustion engine is cold.  <P>SOLUTION: Intake control valves 6 are provided in intake passages 5 per cylinder of the internal combustion engine 1, respectively. The intake control valve 6 is constituted by combining a pair of intake control valves 6a, 6b composed of flap valves capable of being controlled independently of each other to close the intake passages 5a, 5b branched into two parts, respectively. When strong gas fluidity is required while the engine is cold, the intake control valve 6b on one side is normally closed, and the intake control valve 6a on the other side is opened during suction process. Since it is opened while negative pressure develops, speed of intake stream becomes high, and intake stream flows into the cylinder 9 only from the intake passage 5a on one side, strong swirl is generated. In a high load region, both of intake control valves 6a, 6b are opened and closed at timing for obtaining inertia supercharging effect to improve volumetric efficiency.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
