<p>The control device (12) comprises a tubular casing (121), a first dividing wall (122) which has a plurality of holes (122a) and a projecting portion (122b), a second dividing wall (123) which has a throat (123a) and a bypass hole (123c) or channel (123d) (see Figure 5(a)), and (optionally) a third dividing wall (124) which has an orifice (124a). The dividing walls (122,123,124) are rigidly attached to the inner surface of the tubular casing (121). A bellows (125) is mounted on the free end of the projecting portion (122b). An operating valve (126) is mounted on the bellows (125) and is movable by the bellows (125) to throttle refrigerant flow through the throat (123a). The bypass hole (123c) or channel (123d) ensures that, even when the valve (126) has sealed the throat (123a), refrigerant is still able to pass through the second dividing wall (123) and hence through the device (12).</p> |
