A valve (10) is provided that combines the features of a solenoid valve and a check valve into a singel combination solenoid check valve. The valve utilizes a first check valve (58) to allow fluid to flow from the outlet passageway (28) of the valve to a chamber (36) above the piston (40) to ensure that the valve remains closed when the outlet pressure in the valve is greater than the inlet pressure. The valve also utilizes a second check valve (42) that closes a bleed aperture through the piston when the pressure in the chamber above the piston is greater than the inlet pressure. |
