Patent number: 6136196Abstract: An apparatus for directing, controlling, regulating and monitoring flowing liquids, in particular for a membrane-type water conditioning apparatus, is provided, whereby a channel system for the flowing liquid is formed by means of a first body (1) having a surface (2), a plurality of recesses (10a, 10b, 10c, . . . ) provided at the surface and forming channel portions for a flowing liquid and a second body (4) which is non-rotationally connected to the first body and tightly separates the recesses (10a, 10b, 10c, . . . ) from the surroundings, and an inlet and outlet (A, B, C, D, E, F, G, H) for the liquid communicating with the channel portions. This design achieves, in comparison with a conventional pipework, a particularly compact construction. Moreover, a water conditioning apparatus comprising such an apparatus is provided.Type: GrantFiled: October 5, 1998Date of Patent: October 24, 2000Assignee: Grunbeck Wasseraufbereitung GmbHInventor: Helmut Weinberger

Patent number: 4865525Abstract: A metering pump comprises a pump chamber with a diaphragm for delivering a metering agent to a metering point. The pump chamber is adapted to be connected with the metering agent tank through a suction conduit comprising a suction valve. Moreover, a return conduit comprising a head valve is provided.For providing an automatic bleeding or ventilation of the metering pump and the possibility of using the pump also for metering aggressive media, the outlet of the pump chamber is adapted to be connected with the metering point through a second head valve. The outlet is connected with the return conduit and a bleed valve is provided in the return conduit.Type: GrantFiled: August 25, 1987Date of Patent: September 12, 1989Assignee: Grunbeck Wasseraufbereitung GMBHInventor: Hans Kern

Patent number: 4800918Abstract: A tube separator (1) having a shut-off means for separating an inlet side (2) from an outlet side (3) is provided. In order to prevent flutter of the shut-off means (4) in a pressure region changing over the shut-off means, a control valve (10) controlling the shut-off means (4) is provided. The control valve (10) is designed such that the pressure required for changing over from a first opened position to a second shut-off position is smaller than the pressure for changing over from the second into the first position.Type: GrantFiled: August 14, 1984Date of Patent: January 31, 1989Assignee: Grunbeck Wasseraufbereitung GmbHInventors: Hans Arens, Hans Kern, Richard Haslberger

Patent number: 4776771Abstract: A self-aspirating and self-bleeding metering pump comprises a metering chamber having an inlet connected with a predelivery chamber and an outlet connected with a metering point. The predelivery chamber is connected with a metering agent tank through a suction conduit comprising a suction valve and a return conduit comprising a head valve. Furthermore, a diaphragm for predelivering into the predelivery chamber is provided. A metering section of the diaphragm cooperates with the metering chamber for performing the metering stroke and comprises a separate drive serving this purpose. In this manner dynamically stressed sealing members are avoided, whereby the self-aspirating and self-bleeding metering pump is resistent also to the metering of aggressive media.Type: GrantFiled: August 25, 1987Date of Patent: October 11, 1988Assignee: Grunbeck Wasseraufbereitung GmbHInventor: Hans Kern

Patent number: 4624279Abstract: A tube separator (1) having a housing (2) with an inlet (5), an outlet (6) and a separating chamber (14) connectable with a drain (9) is provided. A shut-off member (10) connecting the inlet (5) with the outlet (6) in a first position thereof and separating the inlet (5) from the outlet (6) and connecting the outlet (6) with the separating chamber (14) in a second position is provided between the inlet (5) and the outlet (6). In order to prevent the entry of contaminations into the separating chamber (14) and hence into a line system connectable with the inlet (5) and the outlet (6) the separating chamber (14) is designed in a manner to be tightly sealed against contaminations. To this end preferably a filter (24) is provided between the separating chamber (14) and the drain (9).Type: GrantFiled: August 14, 1984Date of Patent: November 25, 1986Assignee: Grunbeck Wasseraufbereitung GmbHInventors: Hans Arens, Hans Kern, Richard Haslberger

Patent number: 4595031Abstract: A tube separator (1) is provided comprising a housing (2) with inlet connection (13) and outlet connection (14) and a member (37) being disposed within the housing (2) and slidable between a first and a second end position. The member (37) comprises a channel (49) extending from an entrance opening (55) to an exit opening (56) and an area (40') on which the pressure in the inlet connection may act upon. Furthermore, a spring (46) acts upon the member (37) in a direction opposite to the action of the inlet pressure. The channel (49) forms a connection between the inlet connection (13) and the outlet connection (14) in the first end position of the member (37), and the member (37) separates the inlet connection (13) from the outlet connection (14) in the second end position of the member (37). The entrance opening (55) and the exit opening (56) each comprise a straight secant, and their respective secants being parallel to each other.Type: GrantFiled: August 10, 1984Date of Patent: June 17, 1986Assignee: Grunbeck Wasseraufbereitung GmbHInventors: Hans Arens, Hans Kern, Richard Haslberger

Patent number: 4573491Abstract: A tube separator (1) is provided comprising a shut-off means (4) for separating an inlet side (2) from an outlet side (3) as well as a control valve (11) controlling the shut-off means (4) in dependence on the difference of the pressure at the inlet side 2 and the outlet side 3. In order to prevent a flutter of the shut-off means (4) for low flow rates a valve (42) is provided which is designed such that it releases the connection of the outlet pressure with the control valve (11) only if the flow rate of the medium drops below a certain value.Type: GrantFiled: August 14, 1984Date of Patent: March 4, 1986Assignee: Grunbeck Wasseraufbereitung GmbHInventors: Hans Arens, Hans Kern, Richard Haslberger

Patent number: 4572397Abstract: A dirt and bacteria tight connection between a container for chemicals and the suction pipe of a metering pump is disclosed, which may in particular be used for the treatment of drinking water. In this way it is achieved that only degerminated air may enter the interior of the container when sucking metering fluid from the container.Type: GrantFiled: January 28, 1985Date of Patent: February 25, 1986Assignee: Grunbeck Wasseraufbereitung GmbHInventor: Hans Arens

Patent number: 4523903Abstract: A dosing pump (1) is created allowing to accurately dose a medium to be dosed as a function of time or of a flow rate. The dosing pump (1) utilizes a predelivery obtained by a diaphragm (11) as well as a piston-cylinder-pump for dosing. The pump cylinder is connected with the suction conduit so as to prevent any pressure drop when the piston emerges from the cylinder. A crystallization or polymerization of the dosing agent in the piston-cylinder-means is thereby prevented.Type: GrantFiled: November 9, 1983Date of Patent: June 18, 1985Assignee: Grunbeck Wasseraufbereitung GmbHInventor: Hans Arens
