Patent number: 9079701Abstract: A pneumatic dosing unit includes a housing having a first housing part for a pump-fluid receiving pump channel and a second housing part for dosing-fluid receiving channels. A cavity is formed between the housing parts. A flexible diaphragm is clamped between the housing parts and divides the cavity into a pump chamber and a dosing chamber that are fluidically separated from each other. At least one feed channel and at least one drain channel in the second housing part lead to the dosing chamber and start from the dosing chamber, respectively. Diaphragm valves in the feed channel and in the drain channel are spaced apart from the pump chamber and the dosing chamber and are controllable via control channels in the first housing part. The diaphragm and the diaphragm valves are arranged in such a way that dosing fluid does not come into contact with the first housing part.Type: GrantFiled: April 19, 2013Date of Patent: July 14, 2015Assignee: BUERKERT WERKE GMBHInventors: Christoph Hettinger, Volker Lienhardt, John Van Loon

Patent number: 6726173Abstract: The microvalve comprises a drive housing (3) in which a magnetic drive is arranged that includes a solenoid (1) and an armature (6) adapted to be actuated by the solenoid. A flanged housing (2) in which two valve seats (10a, 10b) are formed is mounted against the drive housing. Arranged between the drive housing (3) and the flanged housing (2) is a diaphragm (5) which is adapted to be pressed against the valve seats by means of a commutation rocker (4) coupled to the armature. The commutation rocker (4) has a pivot bearing, the axis (13) of which, for avoiding tolerances, assumes a position which is determined by direct abutment on a seating surface of the flanged housing (2) facing the drive housing (3).Type: GrantFiled: September 11, 2002Date of Patent: April 27, 2004Assignee: Bukert Werke GmbH & Co.Inventors: Christoph Hettinger, Ernst Hochholdinger

Patent number: 6688325Abstract: A modular fluid control system which comprises a plurality of fluid distribution modules each formed of a parallelepiped-shaped module block of similar shape and size and having fluid channels therein is provided. Each module block has at least two porting faces on opposite sides, selected ones of the channels opening on an associated one of the porting faces to form port openings. The module blocks are arranged in an aligned abutting relationship so that selected port openings communicate with each other at abutting porting faces of adjacent module blocks. The modular fluid control system further comprises a frame which surrounds the module blocks and has connector through ports therein aligned with selected ones of the port openings.Type: GrantFiled: May 22, 2001Date of Patent: February 10, 2004Assignee: Burkert Werke GmbH & Co.Inventor: Christoph Hettinger

Patent number: 6495103Abstract: A modular control block for applications in the field of analytical procedures has a plurality of individual elements (2, 5, 15, 19, 20), each having at least one channel for the inflow and for the outflow of fluids, which can be connected to each other by means of suitable connection points. In order to reduce the manufacturing costs of the control block, all individual elements (2, 5, 15, 19, 20) are embodied with the same outer contour and may be arranged in-line or staggered, with different function modes of the control block being achieved by either an in-line or a staggered arrangement of the individual elements (2, 5, 15, 19, 20), or by any desired combination of individual elements (2, 5, 15, 19, 20) arranged in-line and/or staggered.Type: GrantFiled: October 29, 1998Date of Patent: December 17, 2002Assignee: Burkert Werke GmbH + Co.Inventor: Christoph Hettinger
