    Abstract: A check valve comprises a housing, a fluid passage, a seat, a valve member and a stop. The fluid passage extends through the housing. The seat is disposed in the fluid passage. The valve member is positioned in the passage to engage the seat. The stop extends through the housing to engage the valve member. The stop is accessible from outside the housing to adjust a distance the valve member can travel from the seat. In one embodiment, the stop includes a variable stop feature, such as an offset pin or a cam. In another embodiment, the stop includes a pump control valve. In yet another embodiment, the housing includes markings to indicate a position of the stop. The valve member comprises a ball or a poppet in different embodiments.

    Abstract: A pump for use with a material sprayer includes a cylinder, a piston, a pump head, first and second check valves, and an elbow connected to the cylinder. The cylinder and the piston are coaxial with a pump axis. The pump head is configured to make a mechanical connection with the reciprocating drive mechanism so as to allow the reciprocating drive mechanism to reciprocate the piston along the pump axis. The elbow includes a first end, a second end, and an inner fluid channel. The first end is configured to make a fluid connection with the hopper. The second end is configured to be fixed with respect to the cylinder. The inner fluid channel extends from the first end to the second end. The pump head and the first end of the elbow are configured to make mechanical and fluid connections with a single linear motion of the pump.

    Abstract: A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.

    Abstract: A handheld sprayer comprises a housing, a turbine, a spray tip, a hopper and a bleed line. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and is configured to discharge a fluid into the air flow passage. The bleed line is configured to direct a portion of the airflow from the turbine to the hopper. Additionally, a method for spraying a fluid from a handheld sprayer comprises directing a portion of an airflow from a turbine into a hopper to assist in discharging fluid from the hopper into a passage connected to a spray tip and the airflow from the turbine.
