  • High-pressure cleaner with encapsulated motor-pump assembly
    Patent number: 5221193
    Abstract: In a high-pressure cleaner, in which the motor and possibly at least parts of the pump are enclosed in a watertight housing (8), an outwardly opening non-return valve is provided in the wall of the housing. The valve is preferably formed by a number of holes (17) in the wall of the housing, these holes being covered by a taut rubber strap (18). With this arrangement, excess pressures caused by combustible substances in the housing being ignited, such as by commuter sparks or a hot part of the motor, are released, thus avoiding damage to the housing.
