Abstract: Provided are a solid form of a Rho-associated protein kinase inhibitor (6-(4-(4-(1H-pyrazol-4-yl)phenylamino)pyrimidin-2-yl)-1-methyl-1H-indol-2-yl)(3,3-difluoroazetidin-1-yl)methanone or a solvate thereof, a method for preparing the solid form, a pharmaceutical composition comprising the solid form, and a use of the solid form as a Rho-associated protein kinase (ROCK) inhibitor, preferably a selective ROCK2 inhibitor.

Abstract: A baffle plate for a compressor, a compressor, and refrigeration apparatus are provided. The baffle plate has a plate body, a through hole and a connection part. The through hole is formed in the plate body. The plate body extends from the through hole in a direction deviating from the axis of the through hole. The connection part is connected with the plate body and is used for connecting the plate body to a non-rotating member. A fixed baffle plate is arranged in the compressor, to physically block the gas flow and form a space for stabilizing the refrigerant oil or lubricant oil on one side of the baffle plate corresponding to the oil sump. The space can isolate the disturbance from spiral flow of a lower cavity to the oil sump caused by the rotation of the motor when the compressor operates.

Abstract: A compressor and a refrigeration device are provided. The compressor has a shell, a compression assembly, a motor, an oil sump and an oil return channel. The shell defines a cavity. A part of the compression assembly is connected to the shell and located in the cavity. The cavity is divided into a first cavity and a second cavity by the compression assembly. A part of the motor is arranged in the first cavity. A part of the shell located below the central axis of the motor is a first shell. The oil sump is arranged in the second cavity. The oil return channel is arranged in the compression assembly, and is provided with an oil inlet facing the first cavity.

Abstract: A crankshaft, an inverter compressor and a refrigeration device are provided. The crankshaft has a main shaft, a crank, and a crank shaft at an end of the main shaft through the crank. The main shaft has an oil suction inner chamber, and an oil distribution channel penetrating the crank shaft. An outer wall surface of the main shaft has a first spiral oil groove and a second spiral oil groove. One end of each of the first spiral oil groove and a second spiral oil groove is in communication with the oil suction inner chamber. Another end of the first spiral oil groove and another end of the second spiral oil groove are formed as a first hole channel and a second hole channel in communication with the oil distribution channel, respectively.
