Abstract
Disclosed is a constant pressure spraying apparatus in which the motor driven pump piston moves within a pump housing and valve assembly which are carried by a cap or closure for the fluid tank forming the reservoir of fluid to be pumped and sprayed. The cap structure is shaped so as to provide a drain sump for fluid leaking past the pump piston.
