Abstract
A liquid slug protector device for air conditioning and heat pump systems includes a housing having an inlet port, an outlet port, and a cavity. The device further includes a piston disposed in the cavity. The piston has an inflow channel. The device also includes a backing structure disposed in the cavity. The backing structure has an outflow channel, where a first refrigerant flow path from the inlet port to the outlet port includes the inflow channel and the outflow channel. The device further includes a peripheral channel that is at least partially bound by the piston. A second refrigerant flow path from the inlet port to the outlet port includes the peripheral channel and the outflow channel. The second refrigerant flow path is closed when the piston abuts against the backing structure.
