  • Patent number: 11167229
    Abstract: A gas-liquid separator includes: a housing including a gas inlet, a gas outlet, and a water storage section at a lower side of the gas inlet and the gas outlet; a collision wall provided inside the housing to collide with a gas that contains water introduced from the gas inlet to separate the water from the gas by adhering the water thereto while changing a flow direction of the gas; and a downflow wall provided inside the housing to introduce the water falling from the collision wall into the water storage section and change the flow direction of the gas.
    Type: Grant

  • Publication number: 20200324232
    Abstract: A gas-liquid separator includes a housing being supplied with water-containing gas, a gas-liquid separation portion being provided inside the housing and separating water from water-containing gas, a water storage portion being arranged on a bottom portion of the housing and storing water separated by the gas-liquid separation portion, and a valve mechanism enabling discharge of and stop of the discharge of water in the water storage portion via a discharge flow path communicating with the water storage portion. An inner wall of the housing has a guide surface flowing water toward the water storage portion and is provided with a regulating portion regulating staying of water in a vicinity of a flow-in port of the discharge flow path.

  • Patent number: 8688298
    Abstract: A boat propelling system capable of reducing electric power consumption includes an outboard engine main body, a swivel bracket arranged to allow the outboard engine main body to pivot in a right-left direction with respect to a hull, an electric motor arranged in the swivel bracket to pivot the outboard engine main body in the right-left direction, a transmission mechanism arranged in the swivel bracket to transmit a driving force of the electric motor to the outboard engine main body, a locking clutch arranged to lock the transmission mechanism so that the outboard engine main body will not be pivoted in the right-left direction by an external force acting on the outboard engine main body, a steering section arranged to steer the outboard engine main body, a steering angle sensor arranged to detect a steering angle of the steering section, a pivot sensor arranged to detect an actual pivot angle of the outboard engine main body, and an ECU arranged and programmed to control the electric motor based on a resu
