摘要

A fluid sprayer is provided and includes a fluid pump assembly having an outlet path and a motor assembly configured to drive the fluid pump assembly to pressurize fluid. The motor assembly is controlled by a throttle mechanism. The fluid sprayer also includes a fluid pressure control assembly including a mechanical pressure transducer configured to be displaced as a function of fluid pressure in the outlet path. The fluid pressure control assembly is configured to control the throttle mechanism as a function of displacement of the mechanical pressure transducer.
