A device for preventing a "gas-lock" comprising a hollow casing defining a reservoir of given capacity and having a lower portion and a set of three openings, that is a first and a third openings substantially positioned at the lower portion of the casing and a second opening positioned near a bottom of the reservoir; a second connection for connecting a corresponding end of the second channel with the second opening; a third channel having opposite ends, one end being positioned near a portion of the first container that is opposite to the aperture of the first container; a third connection for connecting the opposite end of the third channel with the first opening; a check valve; a fourth connection for connecting the check valve with respect to the third opening and for selectively, enabling the liquid contained in the first container to pass through the third opening; the capacity of the reservoir being sufficient to collect when the first container is turned upside-down to have its third channel above the reservoir, all the liquid that may fill this third channel and allow inside the reservoir a free passage for the gas between the first and second openings. Also relates to an arrangement containing the device and a method use. |
