Abstract
An atomizing nozzle assembly (1) for pneumatically operated cleaning equipment with a nozzle body (2), in which a nozzle pipe (12) can rotate in bearings, is improved with regard to safe function and long service life to the effect that a disc section (24) of a stop element (23) arranged on the inlet side of the nozzle pipe (12) has a smaller outer diameter (26) than the inner diameter (27) of the inlet end (4) of nozzle housing (2) so that an annular gap (28) remains between disc section (24) and nozzle housing (2) through which compressed air (14) can flow and compressed air (15) passes through two bearings (9, 10) for the rotary nozzle pipe (12) helping to remove dirt from the bearings.
Claims17
Atomizing nozzle assembly for pneumatically operated cleaning equipment with a nozzle body including a substantially tubular housing section having an inlet section with an opening configured to be fastened to the cleaning equipment, and a substantially funnel-shaped outlet section having an outlet opening, the assembly further including:
- a bearing near each of the inlet and outlet sections, the bearings at an axial offset to one another;
- a rotatable nozzle pipe having an inlet where pressurized fluid can enter, a main section of the nozzle pipe extending through the bearings, followed, in the area of the outlet section of the nozzle housing, by a transitory section of pipe angled in relation to the main section of pipe, the transitory section leading into a nozzle section whose free end includes a nozzle opening from which pressurized fluid can exit;
- and
- a stop element in the area of the inlet section, the stop element having a substantially annular disc section radially protruding outwardly from the nozzle pipe such that there is a secondary flow path for pressurized fluid from the inlet opening to the outlet opening through an annular gap formed between the annular disc section and the tubular nozzle housing.
A nozzle assembly for pneumatically operated cleaning equipment including:
- a substantially tubular housing having an inlet for connecting to the cleaning equipment and an outlet;
- an inlet side bearing and an outlet side bearing positioned within the housing;
- a nozzle pipe extending through the bearings and thereby rotatable with respect to the housing;
- and
- a stop element mounted to the nozzle pipe including a substantially annular disc section that extends radially outward from the nozzle pipe, the stop element positioned between the inlet and the inlet side bearing,
- wherein a first fluid flow path from the inlet to the outlet is provided through the nozzle pipe and a second fluid flow path from the inlet to the outlet is provided through an annular gap between the stop element and the tubular housing.
Atomizing nozzle assembly for pneumatically operated cleaning equipment with a nozzle body comprising a basically tubular housing section with an inlet end with inlet opening to be fastened to the cleaning equipment, ending into a funnel-shaped extension with an outlet section and outlet opening at the opposite side, with a bearing each at the inlet and outlet side at an axial offset to each other for a rotating nozzle pipe having an inlet end where pressurized fluid, comprising compressed air or a mixture of compressed air and fluid droplets, can enter;
- a main section of the nozzle pipe starting from the inlet end and basically reaching through the bearings in a straight manner followed, in the area of the exit section of the nozzle housing, by an transitory section angled in relation to the axis of rotation of the nozzle pipe, which leads into a nozzle section whose free end features a nozzle opening from which the fluid exits, with the nozzle pipe having a stop element in the area of its inlet end basically having an annular disc section radially protruding to the outside, characterized in that the pipe section around the nozzle pipe of the stop element axially touches an inner ring of the bearing at the inlet side and that a secondary flow path of the fluid can flow through an annular gap formed between the disc section and the nozzle housing and via the bearing at the inlet side into the inner space and further through the bearing at the outlet side.
