Abstract
Abstract The pipeless filling unit for counterpressure bottling machines includes a siphon closure consisting of a bell-shaped stopper projecting with its rim portion into an annular groove. The bell-shaped stopper is fixedly held in position in the liquid discharging channel and has a central boring for guiding an axially displaceable valve tube; the bell-shaped rim portion of the stopper is provided around the whole circumference with a plurality of vertically and radially directed slits for intercepting and rinsing away particles from the discharged liquid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
In a counterpressure bottling machine having a liquid tank, a filling unit comprising a liquid discharging channel projecting into said tank; a valve body connected to said tank and communicating with said liquid discharging channel; a valve tube arranged for reciprocating axial movement in said liquid discharging channel and forming with a valve seat in said valve body a liquid discharging valve; a siphon closure including an annular channel surrounding said valve seat in said annular body, and a stationary bell-shaped stopper secured in position in the liquid discharging channel in said valve body and having an upper part provided with a central opening adapted for guiding for axial movement said valve tube, and a lower part provided with a ring portion which projects into said annular channel of said siphon closure, said lower part having a plurality of vertically and radially directed slits forming a comb-like configuration.
Claim 2
Dependent Claim
148 words
In a counterpressure bottling machine having a liquid tank, a filling unit comprising a liquid discharging channel projecting into said tank; a valve body connected to said tank and communicating with said liquid discharging channel; a valve tube arranged for reciprocating axial movement in said liquid discharging channel and forming with a valve seat in said valve body a liquid discharging valve; a siphon closure including an annular channel surrounding said valve seat in said annular body, and a stationary bell-shaped stopper secured in position in the liquid discharging channel in said valve body and having an upper part provided with a central opening adapted for guiding for axial movement said valve tube, and a lower part provided with a ring portion which projects into said annular channel of said siphon closure, said lower part having a plurality of vertically and radially directed slits forming a comb-like configuration.
Claim 3
Dependent Claim
48 words
A filling unit as defined in claim 1, wherein an upper surface of said lower part of said stopper is located approximately on the level of said valve seat and has a substantially cylindrical shape, and the upper part of said upper surface having an upwardly tapering shape.
Claim 4
Dependent Claim
35 words
A filling unit as defined in claim 1, wherein the central opening in said upper part of said stopper is provided with an axial groove for receiving and guiding a projection in said valve tube.
Claim 5
Dependent Claim
43 words
A filling unit as defined in claim 1, wherein the central opening in the lower part of said stopper has an increased diameter with respect to the upper part to define a stop surface for limiting the upward movement of said valve tube.
Claim 6
Dependent Claim
25 words
A filling unit as defined in claim 1, wherein said bell-shaped stopper is held in position in said liquid discharging channel by radially projecting arms.
