Apparatus for controlling gas temperature in compressors

An apparatus comprising a cylinder for containing gas, a piston for changing the volume of the gas in said cylinder, a plurality of atomisers, each comprising an aperture for admitting liquid therethrough into said cylinder, means for delivering a flow of liquid to said apertures, each atomiser further comprising means defining a flow path for imparting rotary motion to said flow of liquid about the axis of said aperture so that on leaving said aperture the liquid divides into a spray in said cylinder, and wherein the angle between the axis of at least one of said apertures and a line parallel to the axis of said cylinder is different from the angle between the axis of at least one other said aperture and a line parallel to the axis of said cylinder.

A spray apparatus comprising a body adapted for connection to the cylinder housing of a reciprocating gas compressor, a plurality of atomisers mounted in said body and arranged circumferentially around the axis of said cylinder when in use, each said atomiser having an aperture arranged, in use, to spray liquid into said cylinder and further comprising means defining a flow path for imparting rotary motion to said flow of liquid about the axis of said aperture so that on leaving said aperture the liquid divides into a spray in said cylinder, and wherein a said aperture is positioned adjacent another said aperture and the axes of said adjacent apertures are oriented such that their respective sprays intersect at a position proximate at least one of said adjacent apertures.
