Abstract
Abstract A device for filling and emptying reservoirs through a lateral annular orifice providing a high through-put, low-speed fluid flow whose stream lines are slight and substantially equal right around the vertical axis of the device. The device includes a curved duct of constant cross-section whose wall portion on the side of the concavity substantially conforms to the shape of the fluid jet. An end of the duct opens vertically into a shaped diffusing opening covered by a deflector screen spaced from the shaped outlet.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
107 words
A device for filling and emptying reservoirs through a lateral annular orifice providing a high through-put, low-speed fluid flow, the inclinations of whose stream lines are slight and substantially equal right around the vertical axis of the device, comprising a curved duct of varying shape and constant crosssection having a wall portion on the side of the concavity which conforms substantially to the shape of the fluid jet, one end of said duct opening vertically into a shaped diffusing opening, a deflector screen spaced from and covering the shaped opening, and a substantially frusto-conical central portion for said screen coaxial with said one end of said duct.
Claim 2
Independent Claim
107 words
A device for filling and emptying reservoirs through a lateral annular orifice providing a high through-put, low-speed fluid flow, the inclinations of whose stream lines are slight and substantially equal right around the vertical axis of the device, comprising a curved duct of varying shape and constant crosssection having a wall portion on the side of the concavity which conforms substantially to the shape of the fluid jet, one end of said duct opening vertically into a shaped diffusing opening, a deflector screen spaced from and covering the shaped opening, and a substantially frusto-conical central portion for said screen coaxial with said one end of said duct.
Claim 3
Dependent Claim
48 words
A device for filling and emptying reservoirs as described in claim 1, said deflector screen being perpendicular to and of revolution relative to the axis of revolution of the opening, and means for promoting the flow during filling and emptying and comprising a rounded edge on the cover.
