Patent number: 10647562Abstract: A filling valve includes a valve seat, an axially-movable valve tappet extending through the valve seat and having an axial portion that defines a product-delivery space through which filling product flows, and axially-displaced first and second seal-seats disposed so that liquid product flows from the first seal-set, through the product-delivery space, to the second seal-seat and out through an outlet. The first seal-seat and the second seal-seat are arranged on the valve tappet in such a way that, in response to a closing movement of the valve tappet, the first seal-seat closes before the second seal-seat, and wherein the first seal-seat, after having been closed as a result of the closing movement, permits further axial movement of the valve tappet to permit closing of the second seal-seat.Type: GrantFiled: September 17, 2015Date of Patent: May 12, 2020Assignee: KHS GmbHInventors: Ludwig Clüsserath, Max Stolz, Manfred Härtel, Dieter-Rudolf Krulitsch

Patent number: 9950460Abstract: A method and device for producing containers filled with a liquid filling material from preforms made of a thermoplastic material, wherein the respective preform is at least thermally conditioned and subsequently re-formed during a forming and filling phase into the container with at least one liquid filling material as a pressure medium having a filling pressure p2. The filling material or portions of the filling material is/are supplied at at least two points in time and/or during at least two process phases having different carbon dioxide contents and/or different temperatures. The filling pressure p2 of the container formed in the first process phase is reduced to a pressure p1 and filling material is supplied in the second process phase, after which the pressure of the container is reduced to atmospheric pressure p0. In the first process phase filling material that has been previously degassed and/or uncarbonated is supplied.Type: GrantFiled: July 31, 2013Date of Patent: April 24, 2018Assignees: KHS GMBH, KHS CORPOPLAST GMBHInventors: Dieter Klatt, Frank Haesendonckx, Ludwig Clüsserath, Manfred Härtel, Wilfried Ehmer

Patent number: 9902603Abstract: A method for operating a filling machine includes conducting purgative gas via a first controlled gas path from a first ring channel common to all filling elements to the interior of a container sealed against a filling element via a controllable choke arrangement that switches between choking state and non-choking states, draining the purgative gas out of the container's interior through return-gas openings and into return-gas channels of a second controlled gas path, the first and second return-gas channels being controlled by corresponding first and second control valves that are operable independently of each other, and pressure-filling the container with the liquid contents.Type: GrantFiled: March 1, 2014Date of Patent: February 27, 2018Assignee: KHS GmbHInventors: Ludwig Clüsserath, Manfred Härtel, Dieter-Rudolf Krulitsch

Patent number: 9856125Abstract: A filling element includes a filling-element housing and a liquid-carrying duct formed therein that ends in an opening for discharging liquid product into a container. A liquid valve controls flow through the duct. During filling, a return-gas tube extends into the container's interior. An actuator uses the gas tube as a valve tappet to open and close the liquid valve. As it moves the gas tube up and down, the actuator simultaneously controls a first control-valve that controls flow between the return-gas tube and a gas-chamber. The gas chamber is configured for conducting away return gas forced out of the container's interior by incoming filling product during filling thereof, for imposing a filling pressure in the container's interior, for flushing said container's interior with a flushing gas, or for evacuating the container's interior.Type: GrantFiled: April 19, 2014Date of Patent: January 2, 2018Assignee: KHS GmbHInventors: Ludwig Clüsserath, Manfred Hãrtel, Bernd Bruch

Patent number: 9850075Abstract: A method for processing containers in a container-processing machine includes identifying a first container behind an adjacent second container in a container flow, the first container being positioned within the container flow such that the first container will, absent intervention, occupy a first processing position that has been designated as not to be occupied by any container, holding the first container back, thereby causing the first container to move with a second velocity, that is less than the first velocity, forming a gap between the first and second containers, and releasing the first container. As a result of having been held back, will now occupy a second processing position instead of the first processing position.Type: GrantFiled: April 25, 2014Date of Patent: December 26, 2017Assignee: KHS GmbHInventors: Manfred Härtel, Andreas Fahldieck

Patent number: 9604834Abstract: A filler element includes a housing, a channel formed therein, a valve in the channel, an opening downstream from the valve that dispenses content into a container when the valve is open, a tube for fill-level adjustment, a controlled gas channel, and a collection space. The tube, which adjusts a fill level of content in the container, projects past the dispensing opening and extends into an interior of the container during filling thereof. This tube connects to a collection space separated from a content vat from which the content comes through the channel. To adjust the desired fill level, a gas pressure is applied to the interior through the tube, thereby displacing excess content from the container. The controlled gas channel permits the gas to enter the container interior.Type: GrantFiled: November 27, 2012Date of Patent: March 28, 2017Assignee: KHS GmbHInventors: Ludwig Clusserath, Dieter-Rudolf Krulitsch, Manfred Hartel
