    Abstract: A water tank has a container, a micro switch, a limiting assembly and a float. The float is mounted slidably in the container. The limiting assembly has an actuating rod that slides in a direction perpendicular to the sliding path of the float. An inclined guiding track is mounted between the float and the actuating rod to convert the moving direction. Since the actuating rod utilizes the movement to switch the micro switch on and off, the actuating rod and the micro switch need no abutting structures. Therefore, when the actuating rod is moved by an accidental force, the actuating rod self-moves back to its original position once the accidental force is removed. Then the micro switch is switched on again so that the household appliance is restarted without any extra acts by a user.

  • Publication number: 20150090349
    Abstract: A condensate overflow detection device includes a frame, a housing, an affixing device, a surface placement mechanism, a float and an actuator. The housing has a bottom and a plurality of pan engagement side surfaces extending upwardly from the bottom, each of which is disposed at a different angle relative to the bottom surface. The housing defines a vent structure passing therethrough that allows water to pass into the housing. The affixing device clamps a pan engagement side surface to a sidewall of a secondary condensate pan. The surface placement mechanism places one of the pan engagement side surfaces opposite from the affixing device. The float, disposed within the housing, has a first position when no water has entered the housing and a second position when a predetermined level of water has entered the housing. The actuator causes an event when the float is in the second position.

  • Publication number: 20150034175
    Abstract: In at least some implementations, a fuel tank includes a tank body defining a chamber adapted to receive liquid fuel therein, a reinforcement for the tank body to permit the pressure within the chamber to exceed the vapor pressure of a fuel to be received within the chamber, and an inlet to the tank body through which fuel is added to the chamber. The inlet is configured to mate with a refueling nozzle through which fuel is added to the chamber to permit refueling the tank and maintaining the pressure in the chamber above atmospheric pressure.

  • Patent number: 8910675
    Abstract: A method for venting of a liquid tank with a valve, a primary compartment and a secondary compartment which are connected together via a bridge. The valve includes a chamber provided with a cover, which extends at least partly into the tank and is connected via an upper venting aperture to a venting circuit. A first device monitors a level of liquid in the primary compartment. A second device monitors a level of liquid in the secondary compartment. The valve configured to be closed when the first device detects that the level of liquid in the primary compartment is equal to or higher than a first predetermined filling level, and the second device detects that the level of liquid in the secondary compartment is equal to or higher than a second predetermined filling level.

  • Publication number: 20140318639
    Abstract: An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

  • Publication number: 20140209176
    Abstract: A system and method for improving oil-and-water separation in a blended fluid stream are presented. The system includes a pressure reduction device that causes cyclonic flow in the stream. The pressure reduction device may be a wafer-based hydrocyclone or a modified hydrocyclone having an underflow outlet but no overflow outlet. The system may also include a valve that is located upstream or downstream of the pressure reduction device. Both the valve and the pressure reduction device reduce the pressure of the fluid stream while reducing the shearing of oil and water droplets within the stream. As a result, the droplets are more likely to coalesce and less likely to form emulsions, thus improving oil-and-water separation in downstream treatment processes.

  • Patent number: 8757105
    Abstract: A level control system for controlling a liquid level in a vessel containing a two-phase fluid includes a plurality of sensors configured to measure parameters related to the vessel. The parameters include liquid level in the vessel, vapor flow rate leaving the vessel, pressure in the vessel, temperature of the vessel, and feed-liquid flow rate entering the vessel indicative of a state of the vessel. A predictive controller is configured to receive output signals from the plurality of sensors and predict a volume of liquid over a predetermined time period in the vessel based on output signals from the plurality of sensors and a variation in pressure, thermal load, or combinations thereof in the vessel. The controller is configured to generate a liquid level set point of the vessel based on the predicted volume of liquid in the vessel; and further control a liquid level in the vessel based on the generated liquid level set point by manipulating one or more control elements coupled to the vessel.
