摘要
The invention is of a pump for coffee machines which simultaneously carries out the functions of water measurer and heater. The pump consists of a cylinder (1) with a piston (5) inside which sucks the water from a tank and directs it towards the devices it serves, and in which there are electronic devices for the control of the run of the piston (5) and the consequent measurement of the water. Heating takes place by way of a resistance (11) coiled around the cylinder jacket with the whole in turn enveloped by an insulating covering (12). IMAGE
