Solenoid valve

A solenoid valve movable between a first configuration and a second configuration, the solenoid valve comprising:

• a valve body including a valve bore, a control port, a first port, and a second port, wherein the control port is arranged in a nose of the valve body;
• a solenoid actuator coupled to the valve body and configured to selectively actuate a pin extending from the solenoid actuator and into the valve bore;
• a valve insert arranged within the valve bore, the valve insert defining a cavity in fluid communication with the first port and including a poppet seat arranged at a base of the cavity and between the control port and the first port and a ball seat arranged between the control port and the second port;
• a poppet coupled to the pin, the poppet being received in the cavity and movable, by the solenoid actuator, between an open position and a closed position;
• and
• a valve ball slidably received within a ball chamber included in the valve body;
• wherein when the solenoid valve is in the first configuration, the poppet is in the open position to provide fluid communication between the first port and the control port, and the valve ball is configured to engage the ball seat in response to a pressure in the second port;
• and
• wherein when the solenoid valve is in the second configuration, the poppet is in the closed position and in engagement with the poppet seat, and a distal end of the pin engages the valve ball to provide fluid communication between the second port and the control port.

A solenoid valve, comprising:

• a valve body including a valve bore, a control port, a first port, and a second port, wherein the control port is arranged in a nose at a distal end of the valve body;
• a solenoid actuator coupled to the valve body and configured to selectively move a pin between a first position and a second position, wherein the pin extends from the solenoid actuator into the valve bore;
• a valve insert arranged within the valve bore, the valve insert defining a cavity in fluid communication with the first port and the valve insert including a first valve seat arranged at a base of the cavity, a second valve seat, and an annular wall that defines an axial channel extending between the first valve seat and the second valve seat;
• a first valve element coupled to the pin, the first valve element being moveably received in the cavity and movable with the pin to selectively open and close the first valve element relative to the first valve seat to, respectively, provide or inhibit fluid communication between the first port and the axial channel;
• and
• a second valve element selectively engageable by the pin to selectively open and close the second valve element relative to the second valve seat to, respectively, provide or inhibit fluid communication between the second port and the axial channel;
• wherein the valve body further includes an annular chamber in fluid communication with the axial channel and the control port such that movement of the pin, by the solenoid actuator, between the first position and the second position selectively provides fluid communication between the control port and the first port or the control port and the second port, respectively.
