A washing device mounted on a motor vehicle comprises cold water tanks and a high pressure boiler providing water at 100 to 250 bars. A rotary cleaning arm is supplied with the pressurized hot water and has nozzles at its ends directed towards the surface to be cleaned. A protective casing surrounds the rotary cleaning arm. The cleaninig arm can be mounted underneath the vehicle for vertical movement between operative and standby positions. The rotary arm has a rotation axis passing through its center and is provided with a nozzle at each end, the two nozzles being substantially identical, of flat triangular shape and having the same mean general plane. The nozzle therefore deliver two divergent flat jets that are substantially coplanar and which have different angles of attack on the surface to be cleaned. These jets can impinge on the opposite edges of an element of an irregular surface comprising facets perpendicular to the general plane of the surface, such as cobblestones and duckboards.
A washing device mounted on a motor vehicle comprising at least one cold water tank, means carrying water from said at least one cold water tank to means for heating, said means for heating comprising a high-pressure boiler adapted to deliver hot water at a pressure of 100 to 250 bars, means for supplying the pressurized hot water to a rotary cleaning arm fitted with at least one nozzle capable of directing a jet of pressurized hot water to a surface to be cleaned, and a protective casing surrounding said rotary cleaning arm.
A washing device mounted on a motor vehicle comprising at least one cold water tank, means carrying water from said at least one cold water tank to means for heating, said means for heating comprising a high-pressure boiler adapted to deliver hot water at a pressure of 100 to 250 bars, means for supplying the pressurized hot water to a rotary cleaning arm fitted with nozzles capable of directing a jet of pressurized hot water to a surface to be cleaned, said nozzles being of substantially identical flat triangular shape, said nozzles having outlet apertures subsumed by an angle .beta. of 15.degree. 4020 .
A washing device mounted on a motor vehicle comprising at least one cold water tank, means carrying water from said at least one cold water tank to means for heating, said means for heating comprising a high-pressure boiler adapted to deliver hot water at a pressure of 100 to 250 bars, means for supplying the pressurized hot water to a rotary cleaning arm having an axis of rotation, said rotary arm being fitted with two nozzles, one on each side of said axis of rotation, said nozzles being capable of directing a jet of pressurized hot water to a surface to be cleaned, motor means ensuring the rotation of said rotary cleaning arm, the angle of inclination .gamma. of each of said nozzles with respect to the axis of rotation of the rotary cleaning arm being substantially identical and one of the nozzles being directed in the direction of rotation, the other being directed opposite the direction of rotation, so that the angles of attack of jets from said nozzles on the surface to be cleaned are different.
A washing device mounted on a motor vehicle comprising at least one cold water tank, means carrying water from said at least one cold water tank to means for heating, said means for heating comprising a high-pressure boiler adapted to deliver hot water at a pressure of 100 to 250 bars, means for supplying the pressurized hot water to a rotary cleaning arm fitted with at least one nozzle capable of directing a jet of pressurized hot water to a surface to be cleaned, wherein said rotary arm has a vertical axis of rotation, and is mounted on the underside of the vehicle with the nozzle directed at the ground which defines the surface to be cleaned, and a rinsing manifold is provided at one end of said vehicle, said rinsing manifold being pivoted at one end and actuator means being provided spaced from said one end of said rinsing manifold for raising, lowering and angularly moving the rinsing manifold toward and away from the rest of the vehicle.
A washing device mounted on a motor vehicle comprising at least one cold water tank, means carrying water from said at least one cold water tank to means for heating, said means for heating comprising a high-pressure boiler adapted to deliver hot water at a pressure of 100 to 250 bars, means for supplying the pressurized hot water to a rotary cleaning arm fitted with at least one nozzle capable of directing a jet of pressurized hot water to a surface to be cleaned, wherein said rotary cleaning arm is mounted proximate to an end of an articulated arm, and motor means rotating said rotary cleaning arm on said articulated arm.
A washing device mounted on a motor vehicle comprising at least one cold water tank, means carrying water from said at least one cold water tank to means for heating, said means for heating comprising a high-pressure boiler adapted to deliver hot water at a pressure of 100 to 250 bars, means for supplying the pressurized hot water to a rotary cleaning arm fitted with at least one nozzle capable of directing a jet of pressurized hot water to a surface to be cleaned, wherein said rotary arm has a vertical axis of rotation, and is mounted on the underside of the vehicle with the nozzle directed at the ground which defines the surface to be cleaned further comprising means for raising and lowering said rotary arm between a cleaning position in immediate proximity of the ground and a standby position spaced above the ground, raising and lowering movement of said rotary arm being substantially rectilinear and parallel to the vertical axis of rotation.
