Abstract
A paint cup assembly for a paint sprayer is disclosed and includes a cap, a paint reservoir formed with an air inlet port, and a valve assembly disposed within the paint reservoir and engaged with the air inlet, wherein the valve assembly is configured to be operable from a closed configuration, in which air flow through the air inlet port is prevented, and an open configuration, in which air flow through the air inlet port is permitted, upon actuation of a spray gun.
Claims17
A paint cup assembly for a paint sprayer, comprising:
- a cap;
- a paint reservoir having an air inlet port in direct fluid communication with an ambient environment, wherein the paint reservoir has a first end and a second end opposite the first end, wherein the first end is adjacent the cap, and wherein the air inlet port is defined by the second end of the paint reservoir;
- and
- a valve assembly, wherein at least a portion of the valve assembly is disposed between the air inlet port and an internal volume of the paint reservoir such that the valve assembly is in fluid communication with the paint reservoir and engaged with the air inlet port, wherein the valve assembly is configured to be operable from a closed configuration, in which air flow through the air inlet port is prevented, and an open configuration, in which air flow through the air inlet port is permitted from the ambient environment, during actuation of the paint sprayer, wherein the valve assembly comprises a flexible bleeder adjacent to the air inlet port, and wherein the flexible bleeder is configured to move between a closed configuration in which the flexible bleeder blocks the air inlet port and an open configuration in which the flexible bleeder unblocks the inlet port, and wherein the entirety of the flexible bleeder is located inside the paint reservoir.

A paint cup assembly for a paint sprayer, comprising:
- a cap having an outlet;
- a paint reservoir having an air inlet port in direct fluid communication with an ambient environment, the paint reservoir configured to engage the cap, wherein the paint reservoir has a first end and a second end opposite the first end, wherein the first end is adjacent the cap, and wherein the inlet port is defined by the second end of the paint reservoir;
- a first valve assembly in fluid communication with the cap, wherein the first valve assembly is configured to control paint flow through the outlet;
- and
- a second valve assembly in fluid communication with the paint reservoir, wherein the second valve assembly is configured to permit air flow through the inlet port from the ambient environment during actuation of the paint sprayer,
- wherein at least a portion of at least the second valve assembly is disposed between the air inlet port and an internal volume of the paint reservoir,
- wherein the second valve assembly comprises a flexible bleeder adjacent to the air inlet port, and wherein the flexible bleeder is configured to move between a closed configuration in which the flexible bleeder blocks the air inlet port and an open configuration in which the flexible bleeder unblocks the inlet port, and wherein the entirety of the flexible bleeder is located inside the paint reservoir.

A paint cup assembly for a paint sprayer, comprising:
- a paint reservoir comprising:
- a bottom;
- a sidewall extending from the bottom;
- and
- an air inlet port defined by and disposed along the bottom and in direct fluid communication with an ambient environment,
- wherein the paint reservoir is adapted to hold paint;
- and
- a valve assembly, wherein at least a portion of the valve assembly is disposed between the air inlet port and an internal volume of the paint reservoir such that the valve assembly is in fluid communication with the paint reservoir, wherein the valve assembly is configured to permit air flow from the ambient environment through the inlet port into the paint reservoir during removal of paint from the paint reservoir, wherein the valve assembly comprises a flexible bleeder adjacent to the air inlet port, and wherein the flexible bleeder is configured to move between a closed configuration in which the flexible bleeder blocks the air inlet port and an open configuration in which the flexible bleeder unblocks the inlet port, and wherein the entirety of the flexible bleeder is located inside the paint reservoir.
