Abstract: The present invention relates to a caulking gun for dispensing viscous material comprising a stock a cartridge keep a push rod longitudinally moveably mounted in the stock provided at its one end with a plunger which engages the piston of a cartridge placed in the cartridge keep, means for engaging the push rod to advance it, brake means hinged to the stock and provided with a clearance hole for engaging the push rod such that the push rod is moveable in a direction advancing the push rod towards the cartridge and is held in a direction retreating the push rod from the cartridge, which brake means are arranged to travel to a first position relative to the stock as the push rod advances and to a second position as the push rod retreats thereby defining the retreat of the push rod, the brake means being inclined relative to the axis of the push rod and adjusting means for varying the retreat of the push rod.

Abstract: The present invention relates to a valve member for a dispenser valve for foam products, and in particular for a dispenser valve for polyurethane foam container, comprising a valve member that is moveable relative to a sealing. It also relates to such a dispenser valve and to a foam container. In order to provide alternative materials for valve members, it is proposed according to the invention that the valve member is made of plastic material filled with basalt particles in an amount between 1% and 60% by weight. It has been surprisingly found that valve members made of plastic filled with basalt particles in these amounts show improved properties, such as strength and abrasion rates, compared to non-filled plastics and compared to glass-filled plastics.

Abstract: A mounting assembly for mounting an adapter to a valve stem of a valve of a pressurized container for the application of foam, where the adapter is configured to be mounted by means of the female threaded element onto the male threaded element of the valve stem by means of an axial screwing movement up to the mounted position, wherein the adapter further comprises a locking element at the extreme upstream end that is configured, when mounting, under the effect of the axial screwing movement towards the mounted position, to move past the collar and secure the female threaded element in the mounted position.

Abstract: The invention relates to a foam gun, in particular for polyurethane foam, having a body and, fitted thereto, a handle with a triggering device, having a container holder and a fluid connection between said container holder and an outlet opening to which an interchangeable dispensing tip is attachable. To facilitate the carrying along of dispensing tips, it is proposed within the framework of the invention that the handle be designed to accommodate at least one dispensing tip. The handle may be hollow inside and serve to accommodate at least one dispensing tip, preferably several dispensing tips. This is insofar advantageous that the foam gun always includes spare dispensing tips, making it unnecessary to carry these along separately. The dispensing tips are moreover protected until needed from the frequently harsh general conditions prevailing at the place of use, in particular from contamination by chemicals that could trigger an unwanted reaction with the exiting polyurethane foam.

Abstract: A device for dispensing pressurized fluids has a body structure that includes a handle structure with a trigger, a device for securing a container to the body structure and a fluid connection from the device for securing the container to an outlet nozzle of the device. The device for securing the container is designed in such a way that the container main axis is essentially parallel to the axis of the body structure so that the general shape of the device resembles more to a gun or a pistol so as to provide an ergonomic device for dispensing pressurized fluids which can be used in any position and which allows access to any locations in which the pressurized fluid has to be applied. A longitudinally movable needle is provided inside the outlet nozzle which is connected to a device for blocking the movement of the needle.
