Abstract
Abstract The invention relates to an arrangement for dosingly filling of fluent or pasty filling material into a container. The arrangement has a housing in which a control element is rotatably mounted. A feed and outlet passage for the filling material is alternately unblocked and a reciprocating dosing piston is provided in the housing. For purposes of achieving a compact and simple construction and a simple assembly, as well as for achieving a good cleaning, the housing is hermetically sealed on all of its sides and the control element is in the form of a rotational cylinder operatively mounted in the region of the feed and outlet passages for the filling material. The dosing cylinder is coaxially mounted with respect to the rotational cylinder and is provided with a piston rod so that the dosing piston is slidably movable within the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
278 words
An improved arrangement for dosingly filling of fluent or pasty filling material into containers, which arrangement includes a housing having an inlet and an outlet passage for the filling material and cleaning fluid, a control element rotatably mounted in said housing which is adapted to alternately block and unblock said inlet and outlet passages, and a dosing piston which is reciprocally mounted in said housing by means of a piston rod affixed thereto and is coaxial relative to the rotational axis of said control element, the improvement comprising, wherein said housing defines an inner chamber for directly receiving said control element, said inner chamber being accessible via said inlet and outlet passages but being otherwise hermetically sealed; said dosing piston sealing one end of said inner chamber; a first bearing support mounted at one end of said housing; a reciprocally movable piston rod mounted in said bearing support and being rigidly axially connected to said dosing piston, wherein said first bearing support forms a cover for said housing at one end thereof and at the opposite end thereof the control element forms a seal for said inner chamber; said control element is constructed as a rotational cylinder having a wall with interior and exterior wall surfaces, are cylindically shaped, said rotational cylinder is mounted above the said outlet passage, wherein at least the exterior wall surface of said rotational cylinder is frusto-conically shaped, and converges in the direction towards said dosing piston; and said wall of said rotational cylinder extends only over a portion of the periphery and subtends an arc of 165° to 180° and is axially slidably movably mounted along the axis of said rotational cylinder.

Claim 3
Dependent Claim
85 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 1, wherein the exterior diameter of the dosing piston is smaller than the interior of the rotational cylinder and wherein said inner chamber includes a rinsing chamber and said dosing piston and rotational cylinder being simultaneously slidably movable in said ringing chamber, said rotational cylinder being rotatably and axially slidably movably mounted in a second support bearing which is operatively mounted in said housing.
Claim 4
Dependent Claim
53 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 2, wherein said rotational cylinder is adpated to assume a rinsing position, said rotational cylinder being positioned so as to extend over said inlet and outlet passages when in said rinsing position.
Claim 5
Dependent Claim
60 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 3, including rinsing fluid inlet and outlet conduit means in addition to said inlet and outlet passages which conduit means are operatively mounted in at least one of the following: the housing, the cover, and the second support bearing.
Claim 6
Dependent Claim
32 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 4, wherein said rinsing conduit means form a closed fluid circuit.
Claim 7
Dependent Claim
41 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 5, wherein the end wall of said rotational cylinder which confronts said second bearing support defines said rinsing chamber therewith.
Claim 8
Dependent Claim
71 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 6, wherein said inlet and outlet passages extend tangentially relative to said rotational cylinder and the side of said rotational cylinder which faces away from said wall extending over a portion of said rotational cylinder defines a ring channel in said housing which subtends an arc in excess of 180°.
Claim 9
Dependent Claim
54 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 7, wherein said second bearing support is mounted on said housing at the end opposite to the end on which said cover is mounted and defines a small opening between said opposite end.
Claim 10
Dependent Claim
61 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 8, wherein said second bearing support is drivingly coupled via a pin with the rotational cylinder and is axially displaceably mounted to move into a production position towards said dosing piston and in an opposite direction into a rinsing position.
Claim 11
Dependent Claim
41 words
The improvement in the arrangement for dosingly filling of fluent and pasty filling material into containers as set forth in claim 1, wherein said frusto-conically shaped exterior wall surface of said rotational cylinder diverges in the direction towards said dosing piston.
