Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A separator device for removing both solid and gaseous contaminants from fluids, comprising: a wall defining a vortex flow chamber, a plurality of small pores being formed in said wall to permit fluids stripped of gaseous contaminants to pass therethrough; a fluid introduction means for introducing fluid into said vortex flow chamber in a tangential direction of said chamber; a fluid filter system disposed around the axial center of the separator; a gas removal pipe extending into said vortex flow chamber and disposed substantially at an axial center of said vortex flow chamber, a plurality of small pores being formed in said gas removal- pipe for allowing gas-rich fluid to pass therethrough; and fluid outlet passage means for passing fluid stripped of both solid and gaseous contaminants.
Claim 2
Dependent Claim
127 words
A separator device for removing both solid and gaseous contaminants from fluids, comprising: a wall defining a vortex flow chamber, a plurality of small pores being formed in said wall to permit fluids stripped of gaseous contaminants to pass therethrough; a fluid introduction means for introducing fluid into said vortex flow chamber in a tangential direction of said chamber; a fluid filter system disposed around the axial center of the separator; a gas removal pipe extending into said vortex flow chamber and disposed substantially at an axial center of said vortex flow chamber, a plurality of small pores being formed in said gas removal- pipe for allowing gas-rich fluid to pass therethrough; and fluid outlet passage means for passing fluid stripped of both solid and gaseous contaminants.
Claim 3
Dependent Claim
33 words
The separator device of claim 1, wherein said vortex flow chamber has a circular cross-sectional view in every cross-section taken at a right angle along a central axis of said vortex flow chamber.
Claim 4
Dependent Claim
17 words
The separator device of claim 1, wherein said filter system is disposed around said vortex flow chamber.
Claim 5
Dependent Claim
16 words
The separator device of claim 1, further comprising a relief valve provided in said introduction pipe.
Claim 6
Dependent Claim
17 words
The separator device of claim 1, further comprising a relief valve provided in said gas removal pipe.
Claim 7
Dependent Claim
22 words
The separator device of claim 1, further comprising a relief valve provided between the inlet and outlet sides of the filter systems.
Claim 8
Dependent Claim
16 words
The separator device of claim 1, further comprising means for fixing inner contents of said separator.
