摘要： The outlet opening of the air chest is provided with a sleeve for supporting the organ pipe externally of the chest and which acts as a valve seat for the flexible resilient diaphragm of the chest valve. The diaphragm forms one wall of an auxiliary chamber located beneath the sleeve. An electro-magnetic valve controls the communication of the auxiliary chamber to the atmosphere or the air under pressure in the chest. When the auxiliary chamber is in communication with the interior of the air chest the pressures on opposite sides of the diaphragm are equalized around the sleeve and the pressure differential between the atmospheric pressure in the sleeve and the air under pressure in the auxiliary chamber maintains the diaphragm in sealing engagement with the sleeve. When the auxiliary chamber is in communication with the atmosphere, the pressure differential acting on the diaphragm will move the diaphragm away from the sleeve allowing air under pressure to escape from the chest through the sleeve to the pipe of the organ. The chest valve is preferably mounted on the underside of the air chest externally thereof with the diaphragm exposed to the interior of the chest for cooperation with the sleeve.
