The invention relates to a method for draining water from a tank (22), more particularly a clarification tank, wherein water is optionally drained via a draining apparatus while maintaining a substantially constant liquid level (23).

An internal valve includes a valve stem disposed in a valve body, a poppet valve coupled to the stem, and a bleed valve coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and the poppet may shift closed in response to a pressure change. A valve body of the internal valve includes primary and secondary stem guides supported by respective primary and secondary stem struts connected to an inner side of the valve body. The valve body further includes thickened portions extending inwardly toward an axis of the valve body to which the secondary stem struts connect.

The invention relates to a sanitary arrangement, in particular, a mobile sanitary arrangement in a motor vehicle such as a coach, having a wastewater-collection tank which has a floor and a sidewall that enclose a tank interior, and an inlet connection and an outlet device. The outlet device has an outlet opening with a connection coupling for the connection of a suction-extraction arrangement and a suction-extraction channel, which, starting from the outlet opening, extends downward in the direction of gravitational force to an intake opening within the wastewater-collection tank.

A tank tube bracket for a tank comprises a receptacle extending along an axis and receiving a tank tube and a passage adapted to pass a fluid through the tank tube bracket. A distal end of the passage is directed toward the axis of the receptacle.

A leveling nipple for a tank may include a first pipe that includes a curved portion discharging air inside the tank to an outlet pipe when a fluid is supplied to the tank; and a second pipe that discharges air inside the tank to the outlet pipe when the fluid is supplied to the tank and is connected to the curved portion of the first pipe, wherein the second pipe includes a diversion portion that guides the fluid flowing into the second pipe to the first pipe.

A line coupling having a housing which has a tube connection piece and a housing head. A passage duct extends from a first opening, which is formed by the tube connection piece, to a second opening, which is formed by the housing head. A tube connection structure is arranged in the passage duct. The tube connection structure is connected in a form-fitting manner via first coupling means to a first end of an inner tube which extends out of the housing head through the second opening. The section of the passage duct between the first opening and tube connection structure and inner tube form a flow duct for fluid. A container is also disclosed having a container housing which forms a container hollow space and a container opening. The container opening is formed by an outwardly projecting connection piece, and has a line coupling.

A mobile device for discharging a liquid-filled container is disclosed. The device has a closable compartment provided with a closable opening, and an unloading installation in the inner space of the device, coupleable with the container. The unloading installation is able to extract liquid from the container via top unloading and to move it outside of the device, and includes an absorption means for removing liquid vapors which is connectable with the container for the extraction of top liquid vapors. A method for discharging liquid containers, such as unloading benzyl chloride liquid with the mobile device, is described.

In one of its aspects, the present invention relates to a process for forming a flexible liquid-packaging pouch. This process improves fill-accuracy of the flowable material contained in the pouch. Specifically, the invention relates to a process for improving the fill-accuracy of a pouch by incorporating at least one stand-pipe in a balance tank that feeds the pouch with flowable material to be packaged. This invention also relates to such apparatus for improving the fill-accuracy of the flexible liquid-packaging pouch.

A fuel storage assembly for a vehicle includes a fuel tank defining a fuel chamber, a fuel pump module and a vapor pressure detection system. The fuel pump module includes a flange engaged to the fuel tank and a fuel pump assembly supported by the flange and disposed in the fuel chamber. The vapor pressure detection system includes a vapor pressure sensor attached to the flange, a vapor pressure inlet device disposed in the fuel chamber, and a conduit communicating between the vapor pressure inlet device and the vapor pressure sensor.

A fluid connector includes an extending section having a spiked end to pierce a container port. The extending section includes at least one air conduit and at least one fluid conduit therethrough. The extending section further includes first and second abutment members. The first abutment member is adapted to abut a first or air side of the container port upon piercing of the container port, and the second abutment member, which is spaced from the first abutment member, is adapted to abut a second or fluid side of the container port. The fluid connector can further include grasping members extending from the extending section to facilitate rotation of the extending section relative to the container port during piercing thereof. The fluid connector can also include a check valve in fluid connection with the at least one air conduit. The check valve may be positioned within the extending section.
