FLUID CARTRIDGE FOR A PLURAL COMPONENT SPRAYER
First Claim
1. A fluid cartridge for a plural component sprayer, the fluid cartridge the fluid cartridge comprising:
- a cartridge body having a first end and a second end;
a cartridge bore extending axially through the cartridge body between the first end and the second end;
a first material flowpath extending from the second end to the cartridge bore and a second material flowpath extending from the second end to the cartridge bore;
a first fluid check disposed in the first material path proximate a first inlet of the first material path and a second fluid check disposed in the second material path proximate a second inlet of the second material path, the first and second fluid checks disposed to prevent backflow of material through the first and second inlets;
a first side seal disposed in the first material path proximate the cartridge bore, the first side seal including a first seal member and a first side spring biasing the first seal member at least partially into the cartridge bore such that the first side seal is pre-loaded; and
a second side seal disposed in the second material path proximate the cartridge bore, the second side seal including a second seal member and a second side spring biasing the second seal member at least partially into the cartridge bore such that the second side seal is pre-loaded.

Abstract
A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

20. A fluid cartridge for use in a plural component sprayer, the fluid cartridge configured to receive first and second component materials from the plural component sprayer and to receive purge air from the plural component sprayer, the fluid cartridge comprising:
-
a cartridge body defining a cartridge bore; a first seal housing mounted to the cartridge body, the first seal housing including a first post extending rearward from the first seal housing and configured to be received in a first material port to receive the first component material from the first material port; a second seal housing mounted to the cartridge body, the second seal housing including a second post extending rearward from the second seal housing and configured to be received in a second material port to receive the second component material from the second material port; a third post extending rearward from the cartridge body and configured to be received in a purge port to receive purge air from the purge port; a first fluid check disposed in a first material path extending through the first seal housing from the first post to the cartridge bore; a second fluid check disposed in a second material path extending through the second seal housing from the second post to the cartridge bore; a third fluid check disposed in a purge path extending through the cartridge body from the third post to the a purge chamber in the cartridge bore; a first side seal disposed in the first material path proximate the cartridge bore, the first side seal including a first seal member and a first side spring biasing the first seal member at least partially into the cartridge bore such that the first side seal is pre-loaded; and a second side seal disposed in the second material path proximate the cartridge bore, the second side seal including a second seal member and a second side spring biasing the second seal member at least partially into the cartridge bore such that the second side seal is pre-loaded.
