A device for filling bottles with liquid foodstuff in sterile conditions wherein an intermittently driven device is provided with bottle supports arranged successively in a line in the direction of conveyance and which passes through processing stations. The device is arranged in a hygienic chamber having through openings for the containers of the inlet and outlet thereof, including at least one inlet for introducing sterilizing medium in the upper wall of the hygienic chamber. Contiguous bottle supports form a closed area within the upper wall of the hygienic chamber and gas extraction systems are disposed in the vicinity of the bottle openings and on the outside of the hygienic chamber perform as dynamic sluice elements. The growth conditions for microorganisms in the hygienic chamber are hindered even in the event the amount of sterilizing agent is reduced.

Disclosed is a device for intermittently conveying packages which are conveyed in a first moving direction in package carriers ( ) in a first processing plane in positions underneath various treatment stations and are conveyed back in a second return motion plane in a second moving direction that is parallel in relation to the first moving direction, whereby a conveying cycle is formed. The aim of the invention is to enable such a device to be efficient, compact and be operated using simple devices. According to the invention, the respectively superimposed ends of the essentially horizontal first conveyor ( ) in the first processing plane and of the essentially horizontal third conveyor ( ) in the second return motion plane are connected to one another for forming the conveying cycle by means of vertically acting second and fourth lifting conveyors ( ). Each conveyor ( ) has a separate drive ( ). A third loading plane is arranged between the first processing plane and the second return motion plane. The three planes are arranged in an essentially horizontal manner. Each package carrier ( ) is constructed in an even manner and is held in a horizontal position by means of the conveyor cycle. Means for loading and unloading the packages into and/or from the package carriers ( ) are provided in the region of the third loading plane in a loading direction which is parallel in relation to the first moving direction of the packages.

A valve is described for the dosaged filling of fluids in packages, with a housing (,) with feed pipe (,), a mouthpiece (,) on the front face and an outlet device (,), with a closure body (,) able to be driven movably in the housing (,), able to be brought into engagement with a valve seat and having at the front a valve cone (,) and there behind a thickened central part, and with rear sealing devices (,). So that both fluids similar to water and also those with a fibre content can be filled in a dosaged manner without the risk of clogging and at the same time without relative movements between packaging and outlet device (,) a fluid jet with little to no included air is achieved at a low outlet speed, provision is made according to the invention that the thickened central part (,) of the closure body (,) is provided on its peripheral region with a ring of flow ducts (,) extending in the direction of the longitudinal axis of the mouthpiece (,) which, being open toward the front and toward the rear open into the interior (,) formed by the housing (,).

A hydrostatic gear wheel mechanism has two intermeshing gear wheels in the work space of a housing. To continuously rinse the gear wheel and housing surfaces which slide on each other, grooves on the gear wheel convey lubricant from the work space to between the gear wheel front faces and the axial end walls of the work space.
