  • Patent number: 11434857
    Abstract: Various example embodiments relate to an automatic drain system for use with a fluid water separator. The automatic drain system includes a liquid-in-fuel sensor. The liquid in-fuel sensor is configured to detect a liquid level in a water sump. The solenoid has an open state and a closed state. A control unit is configured to activate the solenoid in response to a signal from the liquid-in-fuel sensor. Activation of the solenoid causes the solenoid to go from the closed state to the open state.

  • Patent number: 11415342
    Abstract: A multistage compression system uses refrigerant and oil. The multistage compression system includes a low-stage compressor that compresses the refrigerant, a high-stage compressor that further compresses the refrigerant compressed by the low-stage compressor, refrigerant pipes that introduce the refrigerant compressed and discharged by the low-stage compressor into a suction part of the high-stage compressor, an intercooler, and an oil discharge pipe. The intercooler cools the refrigerant discharged by the low-stage compressor before the refrigerant is sucked into the high-stage compressor. The intercooler is disposed between the refrigerant pipes. The oil discharge pipe discharges the oil in the low-stage compressor. The oil discharge pipe connects the low-stage compressor and a portion of the refrigerant pipes. The portion of the refrigerant pipes is on an upstream side of the intercooler.

  • Patent number: 9115009
    Abstract: There is described a fluid treatment system comprising: (i) a fluid inlet; (ii) a fluid outlet; and (iii) a fluid treatment zone in fluid communication with the fluid inlet and the fluid outlet. The fluid treatment zone comprises a housing within which is disposed a fluid separation section (the separation section may include a single separation device or a combination of two or more similar or dissimilar separation devices) and a fluid radiation section in fluid communication with one another. The fluid separation section removes solids in the fluid and the fluid radiation section irradiates the fluid to deactive microorganisms in the fluid. The fluid separation section and the fluid radiation section are configured to have a substantially common fluid flow path which significantly reduces the space or footprint requirement of and/or significantly reduces hydraulic head loss (pressure drops) in the overall fluid treatment system while allowing the two sections to perform their respective functions.

  • Publication number: 20150144541
    Abstract: A water filter sand level sensor is positioned inside a water filter and detects if a sand level in the water filter is above or below a critical level. The sand level sensor is connected to an indicator outside the water filter that provides a visual or audible signal regarding the sand level in the water filter. The sand level sensor may be a light dependent resistor detecting light from a light emitting diode and having a resistance that decreases with increasing incident light intensity. The sand level sensor also may be an ultrasonic transducer transmitting ultrasonic energy bursts vertically down through the water filter to the sand level and determining a time difference between a transmitted and a reflected signal.

  • Patent number: 9028681
    Abstract: A drainage device for draining liquid out of a closed chamber includes a main body, a piston assembly, and a transmission assembly. The main body defines a receiving chamber and a liquid inlet communicating with the receiving chamber to the closed chamber. The piston assembly is fixed in the receiving chamber of the main body. The transmission assembly is partially received in the receiving chamber. The transmission assembly and the piston assembly cooperatively separate the receiving chamber to a first chamber adjacent to the liquid inlet and a second chamber away from the liquid inlet. The transmission assembly is slidably received in the receiving chamber, thereby causing air pressure differences between the first chamber and the second chamber, to pump the liquid from the closed chamber to the second chamber. The main body further defines a plurality of discharge holes for draining liquid out of the second chamber.
