Abstract: A closing element is for a valve assembly of a compressor unloader, the compressor including a casing with a compression chamber, the unloader including a housing defining a chamber. The valve assembly has a base between the compression and unloader chambers, a passage connecting the two chambers, a seat about the passage, and a stem bore within the base having a control chamber. The closing element includes a main body movably disposed within the stem bore and having a sealing surface disposeable against the valve seating surface to obstruct the valve passage and a control end surface within the bore control chamber. A sealing member disposed about the main body prevents flow between the control chamber and the valve passage. The main body and/or the sealing member is configured such that the main body is radially moveable to align the body sealing surface with the valve seat.
