Abstract:
A vessel for liquids is described, made of plastic material of the keg type, comprising: a delivering tap (1) composed of a main body (7.1); a covering device (9.1) equipped with two turrets (9.3) for entering gas and exiting liquid into/from the body (7.1); two pistons (8.1) operatively coupled to the turrets (9.3) for controlling their opening and closing; two bottoms (10.1) operatively coupled with the pistons (8.1) for controlling their operation; and a tampering-preventing seal (11.1) placed on the covering device (9.1) in order to prevent an undesired external access to said turrets (9.3) with an integrated degassing device (11.8) for degassing the vessel at the end of its life favouring its correct recycling; and a neck (12.2) of the vessel connected to the delivering tap (1) and equipped with internal and external forgery-preventing means (12.3, 12.1) to cooperate with the tampering-preventing seal (11.1).
Abstract:
A pressure regulator (500, 700) comprising a housing (510) formed to include a bore therein, a piston (760) moveably disposed within the bore wherein that piston comprises a first annular lip (762) adjacent a first end, a spring (720) disposed within said bore and comprising a first end and a second end, an adjustment cap (750) moveably disposed in the bore, wherein the first end of the spring (720) is in physical contact with the first annular lip (762) and the second end of the spring (720) is in physical contact with the adjustment cap (750).
