Abstract
A springless valve that is used for a liquid sprayer has a body that has an upstream bore that has three parts with increasingly larger cross-sections. A pin portion of a slide/pin combination moves between an open position and a closed position. In the open position, liquid in the first part of the upstream bore flows into inlets in the third part of the upstream bore, through a central passage, to an outlet to a downstream bore. A linearly-moving slide portion on the slide/pin combination fits within a recess in the body, and has resilient arms that engage front and rear radial faces on a narrowed waist on the pin. The arms extend over opposed sides of the narrowed waist, have tangs that lock onto a lower side of that waist, and rigidly connect the slide portion to the pin portion, enabling a user to move the slide/pin combination axially between the open and closed positions.
