  • Publication number: 20060283985
    Abstract: An ultra-fine spray-jetting nozzle includes a liquid passage (37) and a gas passage (41) that is disposed on a peripheral side of the liquid passage (37) through a partitioning wall and communicates with a jetting port (A). An outer surface of the partitioning wall at a jetting port side thereof is formed sectionally polygonal, long circular or elliptic. A peripheral surface of the gas passage (41) is formed sectionally circular. The outer surface of the partitioning wall having the configuration is brought into contact with the sectionally circular peripheral surface of the gas passage (41) at a plurality of positions to circumferentially divide the gas passage (41) at the jetting side into a plurality of gas passages. A gas jetted from jetting ports (A) of a plurality of the separate gas passages is mixed with a periphery of a liquid jetted from the liquid passage (37) to generate spray.

  • Patent number: 4750515
    Abstract: A liquid storage tank having a feed port is provided with a float valve for opening and closing the same. The float valve includes a float member and a rod member having one end connected to the float member. The other end of the rod member is fitted into a valve seat, which is formed on the inner periphery of a feed pipe constituting the feed port, and is provided with a valve plug portion for opening and closing the valve seat. When the level of the liquid in the tank is lowered together with the float member, the rod member is tilted so that the valve plug portion is partially separated from the valve seat to open the feed port. When the float member is in a position at which the float member supports the rod member in a horizontal position, the valve plug portion is seated on the valve seat to close the feed port. The pressure of the supply of liquid acts on the valve plug portion to urge the valve seat portion against the valve seat.
