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 en...
1. A springless valve that is used for a liquid sprayer and has: a body that has:(a) a front section that has a downstream bore that communicates with a liquid nozzle,(b) a rear section that has an upstream bore that (i) can be attached to a liquid supply line,(ii) has a first part that has a relatively small cross-sectional area that communicates with a liquid supply inlet,(iii) has a second part that is downstream of the first part and has a larger cross-sectional area than the first part, and(iv) has a third part that is downstream of the second part ...
