摘要： A compact and efficient separator for removing both entrained bubbles and dissolved gases from fluid. Fluid containing gases is introduced tangentially into a vortex flow chamber which is disposed at the suction-side of a pump. The fluid, which is stripped of gaseous contaminants, flows out of the vortex flow chamber while gas-rich fluid collected near center of the chamber passes into a gas removal pipe which is communicated to a suction device.

摘要： An oil filter comprising a housing opened at one end, a first separator unit in the housing for removing solid contaminants from the oil, a mount block for the housing and a second separator unit for removing gaseous contaminants. The first separator unit comprises a cylindrical filter element defining a central space therein, and the mount block is formed with a recess in which the second separator unit is disposed. The second separator unit includes a chamber arranged to generate a vortical flow in the oil introduced therein to thereby separate gas-rich oil which gathers in an axially central portion of the chamber, means for introducing the oil from the central space to the chamber, a first outlet member for leading the oil containing little gaseous contaminants and a second outlet member for discharging the gas-rich oil.

摘要： An integrated and compact separator for removing both solid and gaseous contaminants from engine oil. Oil to be cleaned is introduced tangentially into a vortex flow chamber. Oil stripped of gaseous contaminant passes through pores in the outer wall of the vortex flow chamber into a filter system, while gas-rich oil collected near the center of the chamber passes into a gas removal pipe extending in the chamber at its axial center. After solid contaminant is removed by the filter system, the oil is returned to the engine parts to be lubricated.

摘要： A method and apparatus measures the gas bubble content of a flowing fluid on a continuous basis without extracting a sample of the fluid. A flowing fluid flows into a density sensor via a temperature and pressure sensor where the temperature, pressure and density of the fluid are determined. As the fluid exits the density sensor, a second pressure sensor determines the pressure of the exiting fluid. The outputs of the sensors are amplified and then input into a data processor. An operating panel supplies required constant data regarding the fluid and gas. The data processor calculates the gas bubble content using the above information in accordance with a predetermined formula.

摘要： An integrated and compact separator for removing both solid and gaseous contaminants from fluid. Fluid to be cleaned is introduced tangentially into a vortex flow chamber before or after filtration of the fluid. The fluid stripped of gaseous contaminants passes through pores in the outer wall of the vortex flow chamber while gas-rich fluid collected near the center of the chamber passes into a gas removal pipe extending in the chamber at its axial center. After solid and gaseous contaminants are removed by the separator, the fluid flows out of the separator.

摘要： A device for dynamically measuring the bubble content of a flowing liquid is arranged in a conveyance passage for a flowing liquid or provided in a simple bypass for the conveyance passage of the liquid so that the bubble content of the flowing liquid and the bubble quantity of dissolved gas in the flowing liquid can be dynamically measured due to a change in the pressure of the liquid in the passage or the bypass without extracting any of the liquid therefrom.

摘要： An improvement in an oil filter is provided, the oil filter being of the type which comprise a housing opened at one end thereof, a cylindrical first separator unit disposed in the housing for removing solid contaminants from the oil introduced into the housing, and a second separator unit disposed within the first separator unit for removing gaseous contaminants from the oil that has passed through the first separator unit, the second separator unit including a funnel-shaped cyclone defining a chamber arranged to generate a vortical flow of the oil introduced therein to thereby separate gas-rich oil and a removal pipe extending into the chamber along an axial center thereof for discharging the gas-rich oil. The improvement comprises a wall of the cyclone defining the chamber having a lower portion and an upper portion, and a plurality of pores formed in the lower portion for allowing the oil to flow out of the cyclone. The removal pipe includes an upper end portion positioned above the lower portion of the wall of cyclone, the upper end portion being formed with a plurality of orifices for permitting the gas-rich oil to flow into the removal pipe. The pores and the orifices are arranged in such a manner that they do not overlap with each other in the axial direction of the chamber. The improved oil filter ensures a sufficient and smooth separation of the gaseous contaminants from the oil.

The rotary pump includes a rotor secured to the drive shaft for co-rotation therewith and a plurality of cells for feeding the liquid, each cell constituting a separator for gas-rich liquid upon rotation of the rotor. A stationary shaft extends in the axial bore between the rotary pump and the discharging chamber. A connecting arrangement is provided in the drive shaft and stationary shaft for selectively connecting each cell with the discharging chamber. Also provided is an injector for ejecting into the discharging chamber the gas-rich liquid separated in the cells through the connecting arrangement.

An ejector is provided for ejecting the gas-rich liquid separated in each cell through a passage formed in the drive shaft and the rotor. Also provided is a valve in the passage for opening and closing the same, the valve being arranged to operate in response to a pressure in the cell. The gas rich liquid gathers at inner portion of the cell due to a centrifugal force and is discharged by means of the ejector through the passage when the valve is in an open position.

摘要： A gas removable pump for liquid comprising a housing having an inlet for introducing a liquid thereinto and an outlet for feeding the liquid therefrom, a drive shaft extending into the housing, a pump disposed within said housing and secured to the shaft for co-rotatin therewith, the pump dividing in a liquid-tight manner the interior space of the housing into a suction side and a delivery side. A chamber is confined around the shaft within at least one of the suction side and the delivery side of the housing and is arranged to generate a vortical flow of the liquid introduced therein to thereby separate gas-rich liquid which gathers in an axially central portion of the chamber. A collecting space for collecting the liquid containing little gaseous contaminants is provided in at least one of the suction side and the delivery side radially outward of the chamber. The pump further includes arrangements for introducing the liquid from the inlet into the chamber and for discharging the gas-rich liquid outside of the housing. The gas-rich liquid gathers around the shaft and is discharged through a removal passage and orifices formed in the shaft.
