Abstract
A spray tip for a fluid applicator includes a stem configured to be inserted into the fluid applicator. The stem includes a stem pre-orifice portion and an insert receiving portion. The spray tip includes a pre-orifice insert having an inlet and an outlet. The pre-orifice insert is disposed within the insert receiving portion and disposed against a rearward shoulder of the stem.
Claims20
A method of manufacturing a spray tip, the method comprising:
- providing a cylindrical stem having a longitudinal axis defining an axis of rotation;
- creating a channel that extends through the cylindrical stem in a direction transverse to the longitudinal axis of the cylindrical stem;
- widening a part of the channel to define a first portion, a second portion, and a third portion, wherein
- the second portion comprises a frustum that widens as the frustum continues in a direction moving away from the first portion,
- the third portion has a third portion diameter greater than a first portion diameter of the first portion;
- widening a first part of the third portion to define a pre-orifice portion and to form an insert receiving portion, the pre-orifice portion comprising the first portion, the second portion, and a second part of the third portion, the insert receiving portion extending from the pre-orifice portion and to an opening at a first end of the cylindrical stem;
- inserting a pre-orifice insert into the insert receiving portion through the opening at the first end of the cylindrical stem such that the pre-orifice insert is disposed within the insert receiving portion;
- and
- securing the pre-orifice insert into the insert receiving portion.

A method of manufacturing a reversible spray tip for a fluid applicator, the method comprising:
- providing a stem having a longitudinal axis defining an axis of rotation of the stem;
- machining a channel that extends through the stem in a direction transverse to the longitudinal axis of the stem;
- machining a first part of the channel to widen the first part of the channel and to define a first portion of the channel, a second portion of the channel, and a third portion of the channel, wherein
- the first portion comprises a second part of the channel,
- the second portion comprises a frustum that widens as the frustum continues in a direction moving away from the first portion, and
- the third portion extends from the second portion toward a first end of the stem and having a third portion diameter greater than a first portion diameter of the first portion;
- machining a first part of the third portion to define a pre-orifice portion and to form an insert receiving portion, the pre-orifice portion comprising the first portion, the second portion, and a second part of the third portion, the insert receiving portion extending from the pre-orifice portion toward an opening at the first end of the stem;
- inserting a pre-orifice insert into the insert receiving portion through the opening at the first end of the stem such that the pre-orifice insert is disposed within the insert receiving portion and is configured to receive fluid from the second part of the third portion;
- and
- securing the pre-orifice insert into the insert receiving portion.
