Abstract

A rinse device comprising a housing part (120, 130, 180) and a rinse head (140), the housing part having a first end configured to be attached to a supply of pressurised fluid and a second end to which the rinse head is attached, an axis X defined along the housing part from the first end to the second end, the housing part defining a cavity through which the pressurised fluid flows, in use, from the first end to the rinse head, the rinse head being provided with a plurality of openings (200) through which the pressurised fluid is ejected; and wherein the housing part comprises an outer housing tube (130) and an inner piston (180) movable axially relative to the outer housing tube, and a sealed air-filled cavity (125) defined therebetween, and a spring (190) attached at a first end to the outer housing tube and at a second end to the piston, and wherein the rinse head (140) is attached to the piston at the second end of the housing part, such that the spring is biased to hold the piston at a first axial position relative to the outer housing tube until a force exerted by the pressure of the fluid inside the housing part exceeds the sum of an axial force of the spring and the force from the pressure of the air in the air cavity (125), whereupon the piston is extended axially relative to the housing tube against the force of the spring to a second axial position relative to the outer housing tube, the device further comprising a damping orifice (127) defining a passage from the air cavity (125) through the housing tube to an exterior of the device, such that as pressure of fluid inside the housing part increases, air in the air cavity is compressed and caused to exit the air cavity in a controlled manner via the damping orifice.
