Valve assembly for carpet extractor
First Claim
1. A carpet extractor comprising:
- an extractor housing;
a vacuum source mounted on the extractor housing;
a reservoir mounted on the extractor housing for storing and providing a supply of cleaning solution;
a distributor mounted on the extractor housing and communicating with said reservoir for selectively applying the cleaning solution to a floor surface to be cleaned;
a cleaning accessory tool including a cleaning solution supply hose selectively communicating with said reservoir for selectively applying the cleaning solution to a remote surface; and
,a valve assembly mounted on the extractor housing, in fluid communication with the reservoir, the distributor and selectively in communication with the cleaning solution supply hose of the cleaning accessory tool for selectively delivering cleaning solution to at least one of the distributor and the accessory tool.

Abstract
A carpet extractor valve assembly (340,522) alternately directs cleaning solution to a base-mounted spray bar (74,526) or to a remote distributor (438,614) of an accessory tool (16,524). The valve assembly includes an inlet port (344), which receives cleaning fluid from a handle-mounted reservoir (14,574), and first and second discharge ports (400, 442), connected to the spray bar and the accessory tool, respectively. First and second valve members (352,354) include first and second poppets (362, 444), which are biased by a spring (384) to normally-closed positions in which the first and second discharge ports are sealed. A trigger-operated actuation rod (410) actuates the first valve member to release cleaning fluid to the spray bar. A quick connect coupling (464,466,608,610) connects the remote distributor with the second discharge port and opens the second valve member thereby. In one embodiment, a cleaning solution pump (480), mounted in a pump housing (490) over a base assembly A, is coupled between the valve assembly (340) and the remote distributor (438). In another embodiment, a pump (520) is connected between a cleaning solution tank (574) and the valve assembly inlet port and pressurizes cleaning fluid for both the spray bar (526) and the remote distributor (614).

16. A carpet extractor, comprising:
-
an extractor housing; a vacuum source mounted on the extractor housing; a cleaning fluid reservoir mounted, on the extractor housing for holding a cleaning fluid; a distribution bar mounted on the extractor housing for distributing the cleaning fluid to a floor surface to be cleaned; a first fluid line located on the extractor housing communicating the distribution bar with the reservoir; a valve assembly mounted on the extractor housing communicating with the first fluid line for controlling the delivery of cleaning fluid to the distribution bar; a cleaning accessory tool which is selectively connected to the valve assembly for applying cleaning fluid to an above-floor surface; a second fluid line, connected to the cleaning accessory tool for communicating with the valve assembly, wherein the valve assembly controls the delivery of cleaning fluid to the cleaning accessory tool; and
,a pump for pressurizing the cleaning fluid being delivered to the cleaning accessory tool, the pump communicating with at least one of the first fluid line and the second fluid line, said pump being mounted on one of the extractor housing and the cleaning accessory tool. - View Dependent Claims (17, 18, 19, 20, 21)

22. A floor cleaner comprising:
-
a base housing; a vacuum source mounted on the extractor housing; a valve assembly for selectively delivering a fluid through at least a selected one of first and second discharge ports, the valve assembly including; a first discharge valve which selectively seals the first discharge port in a first position and opens the first discharge port in a second position to deliver the fluid from the first discharge port, and a second discharge valve which selectively seals the second discharge port in a first position and opens the second discharge port in a second position to deliver the fluid from the second discharge port; and
,a first distributor mounted on the base housing for applying the fluid to a floor surface, the first distributor being in fluid communication with the first discharge port; and
,an attachment tool, selectively connectable to the valve assembly, the attachment tool including a second distributor for applying the fluid to a remote surface, the second distributor being in fluid communication with the second discharge port when the tool is connected to the valve assembly. - View Dependent Claims (23)
