ABSTRACT:
A pump for delivery of gas-liquid mixtures adapted to be connected to a container for a liquid comprising: suction means adapted to be reciprocated between a first rest position and a second position so as to collect the liquid from the container; a mixing chamber in communication with the suction means so that when the suction means are moved from a first position to a second position, the liquid is collected from the container and conveyed into a mixing chamber; elastic means adapted to displace the suction means back in the first position after that the suction means are moved from a first position to a second position. The elastic means define a variable volume gas chamber in communication with the mixing chamber so that, when the suction means are moved from a first position to a second position, the gas is conveyed into the mixing chamber and a gas-liquid mixture is formed in the mixing chamber.
