Abstract: A combined dispensing and safety valve for use in syphons for foamed cream has a housing which constitutes a cover for the bottle of the syphon and receives a tiltable or reciprocable valving element of the dispensing valve. This valving element has an axial passage for the reciprocable valving element of the safety valve which opens when the pressure in the bottle reaches a preselected threshold value. The axial passage has a smaller-diameter section for the shank and a larger-diameter section for the head of the valve element of the safety valve. The seat for the valving element of the safety valve can be defined by a detachable cup of the valving element of the dispensing valve or by the surface surrounding the smaller-diameter section of the axial passage. The valving element of the safety valve is biased to its operative position by a coil spring which is installed in the larger-diameter section of the axial passage.

Abstract: A regulator having turbulence generating device for controlling thrust. A differential piston (2) is biased by a spring (3) located in a discharge channel (8a) of a medium under pressure. The spring (3) is weighted in such a way that it is compressed at a given pressure within the container so that the differential piston (2) takes a first end position and decreases the opening of the discharge channel (8a) to a minimum. The spring (3) expands proportionally to the pressure drop due to the discharge of the medium (18) from the container and shifts the piston (2) so that the opening of the discharge channel (8a) increases gradually until the piston (2) has reached a second end position as soon as a given minimum pressure has been reached in the container.

Abstract: By the displacement, depending on the pressure change in the container (22), of a piston (8) in order to open or obturate a bore (9) in the product conduit (7), the amount of product flowing per unit of time through the opened valve (1) is maintained constant even when the pressure in the container (22) diminishes. The piston (8) is so displaced by the pressure prevailing in the container (22) via a diaphragm (12) against a restoring force (21) that the bore (9) defines, at the time of the highest pressure prevailing in the container (22), a smallest predetermined opening for the product flow. By an adequate choice of the shape of the bore (9), the thrust of the product flowing through the opened valve (1) can thereby be maintained constant, which leads to a constant quality of atomization of the product (23) through a spray nozzle.

Abstract: A safety pressure reducing regulator for use in systems operable by pressurized gas incorporates multiple safety features which preclude excessive pressure buildup in the system and provide protection against catastrophic failures.

The secondary regulator stage is designed to automatically regulate the supply of the pressurized gas at the intermediate pressure to the pressure control chamber to maintain a desired operating pressure therein. A flexible diaphragm is normally disposed across the pressure control chamber which is adapted to function as a check valve to control communication between the secondary regulator stage and the pressure control chamber.

Abstract: A coupler adaptor is provided for use in operative association with a container and a valve.

The pressurized gas enters the pressure regulator from the coupler adaptor interface passage. In one embodiment, the coupler adaptor remains operatively joined to the pressure regulator without retaining structure due to the balanced gas pressure which results because of the O-rings positioned adjacent the coupler adaptor interface passage.

Abstract: Pressure reducing and safety discharge valve device adapted for use with compressed gas-containing capsules. The valve has a bore therein in which a spool-shaped valve element is disposed for axial reciprocation. In a first terminal position of the valve element the valve element connects a conduit means leading from a gas-containing capsule discharging gas under moderate pressure to a gas-discharge port of the valve. When the pressure of the gas discharged from the capsule increases to a predetermined value, the valve element moves against the opposition of a spring to cut off further discharge of gas from the capsule; when the pressure of the gas discharged from the capsule increases substantially beyond such predetermined value, the valve element moves still further against the opposition of the spring to discharge such gas through a relief port to the atmosphere.

The diaphragm comprises a material which is stretched across a tubular wall of the tubular member in a tensioned condition, and which at a predetermined PSI within the hopper, ruptures whereupon the ruptured pieces of the diaphragm recede radially outwardly against the wall of the tubular housing in a manner to occupy a minimal amount of space thereby permitting the free flow of air into the hopper.

Abstract: A syringe of the slide piston pump type is adapted to overcome a pressure resistance at its outlet as may be provided, for instance, by a filter in communication with the outlet and through which the syringe is to pump a medium, particularly a liquid medium, for filtration.
