摘要:
An apparatus for preventing the drying of at least one nozzle of a fluid dispensing device includes an element providing moist gas, a supply hose for moist gas and a gas controller which forms a space around the nozzle. Moist gas is led into the space around the nozzle from the elements providing gas through the supply hose. Moist gas leaking out of the space is replaced by new moist gas led into the space.

A paint toning machine comprising a container (11, 12) for storing each paint to be fed, such as toning paste or paint, a piston pump (3, 4) arranged in flow communication with the paint in the container for feeding the paint, and driving means (2, 5-10), driven by a servomotor, for driving the piston pump. In the invention, the driving means comprise a device (10) for changing the rotary motion of the shaft (5) driven by the servomotor in different directions of rotation into linear motion moving the piston rod (7) of the piston pump in opposite directions, and a coupling (8, 9) for selectively coupling the piston rod (7) of the piston pump and the shaft (5) driven by the servomotor (2) into engagement via said changing device (10).

The invention relates to a valve assembly especially for a liquid dispensing device. It comprises a valve enclosure body (10), a valve element (13) located in the valve enclosure (10), an operating lever (14) for moving the valve element (13), and an operating lever sealing (15) in a through-hole of the valve enclosure body (10). According to the invention, the operating lever (14) is pivoted to the valve enclosure body (10) on the outside of the valve enclosure, in which case the pivot point is not in contact with the agent flowing through the valve.

The invention relates to a liquid dispensing device comprising at least one pis-ton pump (7), which sucks liquid to be dispensed from a container in a filling cycle and applies said liquid to a target in an emptying cycle and which is driven by an actuator comprising an actuating means (1) that is arranged to move a piston rod (2) between two extreme positions, and a gripper (3) attached to the actuating means (1), which gripper is able to engage with the piston rod (2) so as to move it along with the actuating means. According to the invention, the gripper (3) is made able to engage with the piston rod (2) only in its first extreme position and arranged to disengage automatically from the piston rod in its second extreme position.

The invention relates to a paint toning machine comprising several containers (4) for toning paste, the elevation of the containers being dependent on the amount of the toning paste they contain, and paste feeding devices (6) interacting with the containers for toning paste, the feeding devices comprising a directional valve (12), a pump (11) and a feed nozzle (13) connected to the directional valve, and a flexible connection (19) between the directional valve and the container for toning paste, which connection allows the vertical movement of the container for toning paste and the flow of the toning paste from the container for toning paste via the directional valve to the feeding pump during the suction phase thereof. In order to avoid a previously used difficult hose coupling, an output (20) of the container (4) for toning paste and an input (21) of the directional valve (12), each connected to the flexible connection (19), are placed substantially one on top of the other, the flexible connection being formed of a collapsible fitting (19).

The invention relates to a dispensing device especially for dispensing colour paste. The device comprises a container (1) for storing the colour paste, a pump (3) connected to the container (1), a nozzle pipe (9), and a valve which connects the pump (3) to the container (1) and to the nozzle pipe (9). The valve comprises a valve enclosure (5), a valve element (4) arranged to move in a reciprocating manner in it, and a seat connected to the nozzle pipe (9). According to the invention, an elastic sealing (7) is attached to the valve element (4) for providing a return movement of the valve element after the nozzle pipe (9) has been closed by a percussion-like movement of the valve element (4).

The invention relates to a carousel-type paint toning machine comprising a frame (1); a carousel base (3) arranged rotatably in an upper part (2) of the frame; containers (4) for toning paste, arranged in a circle on the carousel base; means (5) for rotating the carousel base (3); means for mixing the paste in the paste containers, the means comprising a mixer (6) inside each paste container and a rotatable part (7) connected to the mixer and situated below each container; and means (8) for rotating the rotatable parts (7) connected to the mixers. In order to reduce the costs of manufacturing the machine, the carousel base (3) and the means (8) for rotating the rotatable parts (7) connected to the mixers (6) are formed by cutting them from a single plate, the middle of which forms the carousel base (3) and the remaining outer part forms the means (8) for rotating said rotatable parts.
摘要:
The invention relates to a gas-venting arrangement in a paint-toning machine. A dispensing device (20) comprises an at least substantially vertical-shafted dispensing pump (20) connected through a suction pipe (13) to the inside of a colour paste container and through a dispensing pipe (17) to a dispensing nozzle. The pump (20) comprises a dispensing cylinder (21) and inside it a reciprocating displacement element (14). The lower end of the displacement element (14) in the lower extreme position of its dispensing movement is either level with or past the upper edge (15) of the dispensing pipe (17) opening into the dispensing cylinder (21), and the positions of the suction and dispensing pipes (13, 17) and the lower end of the displacement element (14) in said extreme position are such that they together form a substantially horizontal flow path or one ascending in the direction (A) of the dispensing flow.
