Head for kegs of pressurized drinks

A head for kegs of pressurized drinks comprising:

• a body having means for engaging a keg containing a pressurized drink, a guide and a fixed abutment;
• a tubular member having an inner duct to permit passage of the pressurized drink, the tubular member being movable in the guide in the body between a first lowered position for opening a shutter of the keg and a second raised position for closing the shutter;
• a fork for the tubular member between the first position and the second raised position having a pair of tines and a stem, the tines engaged astride the tubular member and rotatably engaged at respective free ends to the body at an opposite side of the tubular body relative to the stem;
• a lever rotatably engaged on the stem against elastic means which locks the fork on the fixed abutment in both the first position and the second position and releases the fork from the fixed abutment for movement between the first position and the second position when actuated:
• wherein first walls on the stem overlap and slidably engage second walls on the lever so that free edges on the second walls remain entirely within a cavity within the stem so as to eliminate any gap between the first walls and the second walls which may change in size where fingers of a user would grip the stem and lever.
