Abstract: A fluid dispensing device has a spool valve in a dispenser housing with a spool in a spool housing and a spool wall around the spool housing with entrance and an exit openings defined therethrough; an entrance channel in the dispenser housing proximate to the spool wall entrance opening; a force applying element in the entrance channel that applies force against the spool wall with entrance and exit ends with the exit end proximate to the spool wall; a hose adapter fitting with an entrance end extending out from and an exit end extending into the entrance and contacting the force applying element with a flow passage extending through it; and fluid communication through the hose adapter fitting flow passage through the force applying element and into an entrance opening in the spool wall; where the force applying element defines a tortuous path through which fluid must travel.
