The invention provides an expansion machine and a refrigeration system with the expansion machine. The expansion machine comprises an air cylinder, a flange and an adjusting assembly. The flange is arranged on the air cylinder, a first storage groove and a first air suction groove are formed in the flange, and the first air suction groove is formed in the first storage groove. The adjusting assembly is arranged in the first storage groove, and is provided with a flowing channel, a first pressure channel and a second pressure channel. At least part of the flowing channel is located between thefirst pressure channel and the second pressure channel, and the outlet end of the flowing channel is opposite to the first air suction groove. At least part of the adjusting assembly is rotationally arranged, the first pressure channel communicates with an expansion pressure cavity of the air cylinder, and the second pressure channel communicates with an exhaust pressure cavity of the air cylinder, so that at least part o
