ABSTRACT:
A dispensing piston-cock for ice-cream machines comprises a baseplate and a cylinder, both made of plastic material. The cylinder is open at one end and has an ice-cream dispensing hole at the opposite end which is integral with the baseplate. A communication duct formed in the baseplate opens near the lower end of the cylinder and a piston is slidably mounted in the cylinder to reciprocate from a first position where it closes the communication duct and a second position at which the lower end of the piston is raised above the communication duct. The lower portion of the piston at least up to a height to cover the communication duct in the lower position of the piston is covered by a metal jacket.
