    Abstract: A method of controlling the primary device through the input from the slave device. It comprises storing the control information from the user by the slave device. The control information is then sent to the primary device by the slave device in response to the inquire command from the primary device. And the primary device controls the executing of the application based on the control information from the user, wherein the application relates to the control information from the input of the user.

    Abstract: A controlling method of a rotary compressor. Two or more cylinders (12,13) with different volumes are disposed in the compressor (1). In each cylinder (12,13) are respectively provided a piston (14.1,14.2), an eccentric crankshaft (17) for driving the piston (14.1,14.2) to rotate, and bearings (18.1,18.2) for supporting the eccentric crankshaft (17). A spring-loaded sliding vane (16.2) is disposed within a sliding vane slot (15.2) of at least one cylinder (13). The cylinders (12,13) carry out capacity switching in the way of compression and non-compression, wherein the cylinder compressing operation is referred as Mode One and the cylinder non-compressing operation is referred as Mode Two. A valve device (8) is provided outside of the compressor (1), which switches the sliding vane chamber pressure of the cylinders (12,13) between a high pressure and a low pressure via a high pressure and a low pressure which are brought by the compressor (1) during its operation. During its whole operation, the compressor (1) adopts one or more of seven operation ways to operate, singly or in combination, thereby controlling the capacity and freezing ability of the compressor.

    Abstract: A discharge valve device of a rotary compressor includes two or more cylinders (11, 12) disposed in a casing (2), pistons (16, 17) and sliding vanes (18, 19) provided in the cylinders (11, 12), and a main bearing (21) and an auxiliary bearing (22) for supporting an eccentric crankshaft (20). Two or more eccentric portions (23, 24) are provided on the eccentric crankshaft (20). A middle partition (13) is disposed between the upper cylinder (11) and the lower cylinder (12), which consists of one or more plates and is provided with a discharge chamber (31) for placing multiple discharge valves (32, 33) and an upper discharge hole (44.1) and/or a lower discharge hole (44.2). The discharge valves (32, 33) comprise an upper discharge valve plate, a lower discharge valve plate and a middle stopper plate (46). Free ends of the upper and lower discharge valve plates are respectively pressing on the upper and lower discharge holes (44.1, 44.2). The stopper plate (46) has a U shape or V shape or X shape, wherein its sides are pressing on the discharge valve plates, its two ends are fixed in the discharge chamber (31) of the middle partition (13) with two fixed ends of the upper and lower discharge valve plates, respectively, and its middle portion is disposed near or between the upper and lower discharge holes.
