Claim:
An air-assisted sprayer comprising: a platform; a fluid cup connected to the platform to hold a volume of fluid; an air reservoir extending through the platform and configured to receive pressurized air; a spray cap connected to the platform to receive pressurized air from the air reservoir; a pressure line connecting the air reservoir with the fluid cup to pressurize the volume of fluid; a fluid reservoir extending from the fluid cup to the platform to provide pressurized fluid to the spray cap; and a poppet valve in fluid communication with the pressure line between the volume of fluid and the air reservoir to prevent fluid from entering the air reservoir, wherein the poppet valve comprises: a first housing comprising: a first fitting for connecting to the pressure line; and a first body extending from the first fitting; a second housing comprising: a second fitting for connecting to the pressure line; and a second body extending from the second fitting and connected to the first body to define a valve cylinder extending between the first and second fittings; and a spring-actuated poppet assembly disposed within the valve cylinder to permit on-way fluid flow, the spring-actuated poppet assembly comprising: a valve seat threaded into the first housing, the valve seat comprising: a central bore; a shoulder disposed within the central bore; and a poppet seat disposed adjacent the central bore; a poppet comprising: a poppet head configured to rest within the poppet seat; a seal channel extending into the poppet head; a resilient member extending from the poppet head through the central bore; and a hook extending from the resilient member; an o-ring disposed within the seal channel; and a valve spring disposed between the hook and the shoulder.
