A device in a valve includes a valve housing with at least a first and a second fluid port. A closure element including a sealing portion and a diaphragm is arranged in the valve housing. The sealing portion is movable between an open position and a closed position. The closure element and valve housing form a flow passage which communicates with the fluid ports when the sealing portion leaves the closed position. A second sealing portion is arranged in contact with a support portion of the valve housing. An abutment element is arranged in contact with the second sealing portion. The abutment element transmits a force via the second sealing portion toward the support portion to provide a seal. The force is at least partly exerted by a spring element.

Sealing means, kit and method for sealing of hollow hoses of flexible material
The present invention relates to sealing means made of a plastically deformable material for mechanical sealing of hollow hoses (2) of elastic material by means of an appliance having at least two jaws, at least one of which is movable towards and away from the other and which, when moving towards each other, crimp the sealing means against the hose (2) for contamination-tight sealing of the same, the sealing means (20) comprises at least one sealing member (4, 4′; 44, 44′; 64, 64′; 74, 74′; 84), which has two opposite ends and an opening (40, 40′) that extends between said ends to allow the at least one sealing member to be slipped onto the hose (2) to be sealed.
The present invention also relates to a kit comprising a sealing means and an appliance for sealing of hollow hoses and to a method for mechanical sealing of hollow hoses.

A device in a valve (1) includes a valve housing (2) with at least a first (3) and a second (4) fluid port. A closure element (5) including a sealing portion (15) and diaphragm (30) is arranged in the valve housing (2). The sealing portion (15) is movable between an open position and a closed position. The closure element (5) and valve housing (2) form a flow passage (11) which communicates with the fluid ports when the sealing portion (15) leaves the closed position. A second sealing portion (14) is arranged in contact with a support portion (25) of the valve housing (2). An abutment element (16) is arranged in contact with the second sealing portion (14). The abutment element (16) transmits a force via the second sealing portion (14) toward the support portion (25) to provide a seal. The force is at least partly exerted by a spring element.

A device for cutting/shearing in a process vessel (1) product clusters and/or materials (3) into smaller particles and dispersing them in a liquid product bulk (4) or for mixing in the process vessel liquid products with each other that are difficult to mix. The device has an electric motor (13) arranged out-side the process vessel and, driven by the same by magneto drive, a processing unit (12) positioned inside the process vessel. The processing unit comprises a stationary inner part (14) and, rotatable about this, an outer part (15), the inner and outer parts having the shape of substantially concentric rings (16, 17) arranged with a close fit to each other and having a plurality of through slotshaped shearing recesses (18) opposing each other. The products that are to be cut/shorn and/or mixed are suppliable to the area of the common centre axis (20) of the rings and are thrown out through the shearing recesses while being shorn into pieces in order to leave the processing unit through the ring of the outer part, which ring also contributes to rotating the products in the process vessel around the processing unit.
A syringe for a fluid comprises a cylinder, a piston portion arranged in the cylinder and slidable on its inside, and an operating means connected to the piston portion for sliding thereof. The operating means projects from a first end of the cylinder and the cylinder has at a second end an inlet and outlet part for said fluid. Moreover a sealing means is connected in a contamination-free manner to the cylinder in the area of the first end thereof and extends into the cylinder to isolate, sealed against contamination, the inside of the cylinder from the environment.
