摘要： A device for dynamically measuring the bubble content of a flowing liquid is arranged in a conveyance passage (1) 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 oil filter comprising a housing opened at one end, a first separator unit in the housing for removing solid contaminants from the oil and a second separator unit for removing gaseous contaminants. The first separator unit includes a cylindrical filter element and upper and lower end plates attached to the upper and lower ends of the filter element. The second separator unit is disposed in the space defined by the inner periphery of the filter element and between the upper and lower end plates. It includes a chamber arranged to generate a vortical flow of the oil introduced thereof to thereby separate gas-rich oil which gathers in an axially central portion of the chamber, a first outlet for discharging the gas-rich oil and a second outlet for the oil containing little gaseous contaminants, the first and second outlets extending into the housing from the open end thereof.

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.

摘要： An oil filter is provided, the oil filter being of the type which comprises a housing (10) opened at one end thereof, a cylindrical first separator unit (A) disposed in the housing for removing solid contaminants from an oil introduced into the housing, and a second separator unit (B) 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 (B) including a funnel-shaped cyclone (38) defining a chamber (42) arranged to generate a vortical flow of the oil introduced therein to thereby separate gas-rich oil and a removal pipe (50) extending into the chamber (42) along an axial centre thereof for discharging the gas-rich oil. A plurality of elongated pores (54) are formed in a wall of the cyclone (38) defining the chamber (42) for allowing the oil containing little gaseous contaminants to flow out of the cyclone (38). The elongated shape of the pore (54) enables reduction in the number of pores to be formed without affecting the gas separating function and, therefore, facilitates manufacture of the cyclone both in the work and cost involved.

摘要： An integrated and small relief valve both for regulating fluid pressure and removing gaseous contaminants from a fluid. A fluid to be regulated in pressure and to be cleaned is introduced tangentially into a vortex flow chamber. A fluid stripped of gaseous contaminants passes through small pores in the wall of the vortex flow chamber and is collected in a fluid collecting chamber outside the vortex flow chamber and then flows out through an outlet pipe from the collecting chamber. The gas-rich fluid collected near the center of the vortex flow chamber flows into a relief valve pipe extending into the chamber at its axial center, then passes through a relief valve and is removed from the fluid system.

摘要： A gas removable pump for liquid comprising a housing (10) having an inlet (34) for introducing the liquid thereinto and an outlet (62) for feeding the liquid therefrom, a drive shaft (24) extending into the housing and a rotary pump (22) disposed within the housing, the rotary pump including a rotor (30) secured to the drive shaft (24) 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. An ejector (82) is provided for ejecting the gas-rich liquid separated in each cell through a passage (70) formed in the drive shaft and the rotor. Also provided is a valve (108) in the passage (92, 94) for opening and closing the same, the valve (108) 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 method and apparatus for measuring the gas bubble content of a flowing fluid on a continuous basis and without having to extract a sample of the fluid. A flowing fluid flows into a density sensor (5) and pressure sensors (7) are disposed at the entrance (3) and exit (4) of the density sensor (5), and a temperature sensor (6) is disposed at the inlet (3) to measure the temperature of the flowing fluid. An operating panel (12) supplies required constant data regarding the fluid and gas. A data processor (10) calculates the gas bubble content using the above information in accordance with a predetermined formula.
