Abstract: An embodiment of the invention relates to an apparatus for dispensing liquid, which apparatus detects an object and controls the dispensing of liquid. The apparatus includes a first signal source which generates a first beam pulse and a second signal source which generates a second beam pulse and the propagation paths of the beam pulses intersect in relation to each other. The apparatus also includes a receiver which receives reflected parts of the first beam pulse and receives reflected parts of the second beam pulse, the parts reflected from the first and second beam pulses being reflected from the object which is located on the propagation path of the first and the second beam pulse. Furthermore, the system comprises a signal processing unit detects said object based on the parts reflected from the beam pulses and, based on this detection, controls the dispensing of liquid.

Abstract: According to an embodiment of the invention, the invention relates to an apparatus for dispensing liquid, which apparatus is arranged to detect an object (103, 203, 506) and to control the dispensing of liquid. Said apparatus includes a first signal source (101, 201, 502) which is arranged to generate a first beam pulse (102, 202, 504) and a second signal source (108, 208, 503) which is arranged to generate a second beam pulse (109, 209, 505) and the propagation paths of said beam pulses intersect in relation to each other. Said apparatus also includes a receiver (105, 205, 507) which is arranged to receive reflected parts (104, 204) of said first beam pulse and which is arranged to receive reflected parts (110, 215) of said second beam pulse, the parts reflected from said first and second beam pulses being reflected from said object which is located on the propagation path of the first and the second beam pulse.

Abstract: The invention relates to a material-flow controlling magnetic valve (1), comprising a material inlet connection (3), an outlet connection (4), at least one sealing surface (12), and an element (6) movable relative to the sealing surface (12), which, in itself or through the use of a blocking member (11) movable together therewith, is in cooperation with said sealing surface (12) establishing a port (15) between the inlet connection (3) and the outlet connection (4), the element (6) having its movement controlled by means of at least one solenoid (10), and that a housing (5), established in the valve (1) and defined by the moveable element (6), is connected by way of a first flow channel (7) controlled by the first solenoid (8) with a material supply side and by way of a second flow channel (9) controlled by a second solenoid (10) with a material discharge side, wherein, by setting the housing's (5) volume and at the same time the element's (6) position as desired by means of the solenoids (8, 10), the control
