An engine system comprising: a compressor coupled to an engine and supplying air to an intake manifold; a throttle controlling the supply of air from the compressor to the intake manifold; a vacuum reservoir; an aspirator having its motive section in fluid communication downstream of the compressor and its discharge section in fluid communication upstream of the compressor, wherein a suction port of the aspirator is in fluid communication with the vacuum reservoir; a compressor recirculation valve having a pneumatic control chamber, wherein the pneumatic control chamber is in fluid communication with downstream air from the compressor, at a position upstream of the throttle, and wherein the pneumatic control chamber is in fluid communication with the vacuum reservoir; a gate valve having a control port in fluid communication with a pneumatic control chamber of the gate valve to control the opening and closing of a first outlet port of the gate valve and of a second outlet port of the gate valve, wherein the control port is in fluid communication with air entering the intake manifold via a conduit at a position downstream of the throttle, and wherein a gate portion of the gate valve controls fluid communication of the pneumatic control chamber of the compressor recirculation valve with the downstream air from the compressor through the first outlet port and with the vacuum reservoir through the second outlet port; and a bleed line having a bleed valve in fluid communication with the air induction system upstream of the compressor, wherein the bleed line has a junction with a fluid stream flowing from the first outlet port or the second outlet port of the pneumatic gate valve to the pneumatic control chamber of the compressor recirculation valve. a compressor coupled to an engine and supplying air to an intake manifold; a throttle controlling the supply of air from the compressor to the intake manifold; a vacuum reservoir; an aspirator having its motive section in fluid communication downstream of the compressor and its discharge section in fluid communication upstream of the compressor, wherein a suction port of the aspirator is in fluid communication with the vacuum reservoir; a compressor recirculation valve having a pneumatic control chamber, wherein the pneumatic control chamber is in fluid communication with downstream air from the compressor, at a position upstream of the throttle, and wherein the pneumatic control chamber is in fluid communication with the vacuum reservoir; a gate valve having a control port in fluid communication with a pneumatic control chamber of the gate valve to control the opening and closing of a first outlet port of the gate valve and of a second outlet port of the gate valve, wherein the control port is in fluid communication with air entering the intake manifold via a conduit at a position downstream of the throttle, and wherein a gate portion of the gate valve controls fluid communication of the pneumatic control chamber of the compressor recirculation valve with the downstream air from the compressor through the first outlet port and with the vacuum reservoir through the second outlet port; and a bleed line having a bleed valve in fluid communication with the air induction system upstream of the compressor, wherein the bleed line has a junction with a fluid stream flowing from the first outlet port or the second outlet port of the pneumatic gate valve to the pneumatic control chamber of the compressor recirculation valve.
