Wet type suction cleaners
First Claim
1. A wet type suction cleaner comprising a tank having an inlet for suction-induced air flow and an outlet leading to a fan for creating the suction:
- and a float valve assembly including a housing and a float member movable relative to the housing to cause closure of the outlet;
wherein the inlet directs the suction air flow to impinge on an impingement surface part of the housing, and the housing has an opening leading to the outlet which opening is at a part of the housing facing away from the inlet, the housing further being provided with deflecting means for deflecting impinged matter away from the opening, wherein the deflecting means comprises a wall formation extending outwardly from the external surface of the housing, between the opening and the impingement surface.

- and a float valve assembly including a housing and a float member movable relative to the housing to cause closure of the outlet;
- 11. A float valve assembly for fitting in a wet-type suction cleaner, comprising a housing having or adapted for co-operation with an outlet port, a float member movable relative to the housing to cause closure of the outlet port, an impingement surface on the housing exterior and facing in a first direction, an opening in the housing exterior, leading to the outlet port, the opening facing in a direction generally opposite to that faced by the impingement surface, and a deflecting means for deflecting matter from the impingement surface away from the opening in the housing, wherein the deflecting means comprises a wall formation extending outwardly from the external surface of the housing, between the opening and the impingement surface.
