A solenoid valve comprises first, second, and third ports. The solenoid valve further comprises an armature movable between a first position in which fluid flow from the second port to the third port is blocked and fluid flow from the first port to the third port is unblocked and a second position in which fluid flow from the second port to the third port is unblocked and fluid flow from the first port to the third port is blocked. The fluid flow in the second position is blocked until fluid pressure at the first port exceeds fluid pressure at the third port by a predetermined amount to thereby provide check valve functionality. The check valve functionality is integral to the armature. The solenoid valve also comprises an energizeable solenoid that, when energized, moves the armature from the first position to the second position.

Solenoid valve with an integrated check valve functionality for an air braking system of a heavy vehicle

Various embodiments of a flow diverter, a valve and a method of controlling air flow in the valve are disclosed. The flow diverter has a cylindrical body, a plurality of circumferentially spaced apart longitudinal members, an open end portion, a closed end portion and a raised element extending outwardly from the closed end portion. The flow diverter is disposed in a cavity in the valve. The cavity is in communication with a supply passage, an exhaust passage and a delivery passage. Air passes through the flow diverter to the delivery passage when the flow diverter is in a delivery position. Air moves the flow diverter from the delivery position to an exhaust position when air pressure in the delivery passage is greater than air pressure in the supply passage. The flow diverter restricts air from passing from the delivery passage to the supply passage when in the exhaust position.
