PDF COMPRESSOR UNLOADER SYSTEMS - PSG DoverPDF
When the unloader pressure is vented, the unloader piston and actuator rod move away from the suction valve, allowing it to operate normally. The compressor is now 'Loaded' and operates at full rated capacity. The unloader pressure is controlled by a 3-way solenoid valve which is normally positioned via a signal from a pressure switch or timer.

What is an unloader valve? - Rutland Pumps Ltd
A trapped pressure unloader is a simple valve with a spring mechanism mounted in a Brass or stainless steel body. There is a channel within the body that gives water access to the back of a piston. When the trigger is released the pressure against the piston increases and pushes the spring open to allow the water to pass into the bypass.
