  • Patent number: 4669639
    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.
