Abstract
Abstract Device for driving a secondary fluid by a primary fluid comprising a first intake pipe for the primary fluid and a second intake pipe for the secondary fluid which is coaxial to the first pipe, at least one symmetrical bulb is lodged coaxially in the second pipe, with the downward end of the first pipe providing a slit between it and the upward portion of the bulb for the flowing of the primary fluid therethrough whereby the primary fluid issues from the slit in a path substantially tangential to the outer profile of the bulb from upward to downward, the downward end of the bulb being truncated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
Device for driving a secondary fluid by a primary fluid comprising a first intake pipe for the primary fluid and a second intake pipe for the secondary fluid which is coaxial to the first pipe, at least one symmetrical bulb lodged coaxially into the second pipe with its maximum diameter disposed on the upward side of the intake pipes, the downward end of said bulb being truncated, said first pipe entering axially into the upward front portion of said bulb and extending into a channel opening tangentially through the outer wall of said upward front portion of said bulb, a gap between the downward end of said first pipe and the upward portion of said bulb, said gap being so arranged that the primary fluid flowing therethrough circulates in a substantially tangential flow along the oUter profile of the bulb from upward to downward.
Claim 2
Dependent Claim
144 words
Device for driving a secondary fluid by a primary fluid comprising a first intake pipe for the primary fluid and a second intake pipe for the secondary fluid which is coaxial to the first pipe, at least one symmetrical bulb lodged coaxially into the second pipe with its maximum diameter disposed on the upward side of the intake pipes, the downward end of said bulb being truncated, said first pipe entering axially into the upward front portion of said bulb and extending into a channel opening tangentially through the outer wall of said upward front portion of said bulb, a gap between the downward end of said first pipe and the upward portion of said bulb, said gap being so arranged that the primary fluid flowing therethrough circulates in a substantially tangential flow along the oUter profile of the bulb from upward to downward.
Claim 3
Dependent Claim
156 words
Device for driving a secondary fluid by a primary fluid comprising a first intake pipe for the primary fluid and second intake pipe for the second fluid, both pipes being coaxial, a bulb unit disposed coaxially within said pipes, said unit comprising at least two bulbs with the maximum diameter disposed on the upward side of the intake pipes and decreasing from the upward bulb to the downward bulb, a curved connection between the downward end of the upward bulb and the upward front end of the next downward bulb, the downward end of said downward bulb being truncated, a slit between the downward end of the first intake pipe and the upward front portion of the upward bulb, whereby the primary fluid issues from the slit in a path substantially tangential to the outer profile of the upward bulb from upward to downward and follows then the connection and the profile of the downward bulb.
Claim 4
Dependent Claim
156 words
Device for driving a secondary fluid by a primary fluid comprising a first intake pipe for the primary fluid and second intake pipe for the second fluid, both pipes being coaxial, a bulb unit disposed coaxially within said pipes, said unit comprising at least two bulbs with the maximum diameter disposed on the upward side of the intake pipes and decreasing from the upward bulb to the downward bulb, a curved connection between the downward end of the upward bulb and the upward front end of the next downward bulb, the downward end of said downward bulb being truncated, a slit between the downward end of the first intake pipe and the upward front portion of the upward bulb, whereby the primary fluid issues from the slit in a path substantially tangential to the outer profile of the upward bulb from upward to downward and follows then the connection and the profile of the downward bulb.
Claim 5
Dependent Claim
33 words
In a device as claimed in claim 2, means to provide a slit around the slightest diameter of the connection between two successive bulbs and the upward front portions of the following bulb.
