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.
