FIELD: hydraulic devices; fountains. SUBSTANCE: fountain has inlet with liquid supply regulator connected to control unit, storage cavity communicated with unit of tangential passages and circular liquid discharge directed towards axis of symmetry of structure in such way that generatrix of taper surface enveloping the initial section of separate jets escaping from circular discharge or taper surface formed by initial section of united jets escaping from circular discharge is inclined relative to horizontal plane at angle alpha from -90 to 90 deg. In one particular case, fountain may be provided with body including storage cavity, circular connector and pressure chamber; tangential passage unit is sectional; it consists of upper and lower parts; at least one part is profiled and one part is connected to control unit to ensure motion; circular discharge is made in form of closed slotted nozzle which may be sectional consisting of upper and lower parts; one part is connected to control unit to ensure required amount of clearance of slot. EFFECT: extended range of application; enhanced stability and controllability of shape of jets. 11 cl, 20 dwg
