Abstract
Mechanical actuating device for opening or closing a valve of at least one nozzle, the nozzle moving along a path preset with respect to a support. The valve comprises a mobile control unit which is movable between an open position and a closed position, and elements for mechanically moving the control unit including at least one guide rail fitted with a flexure in the area of the open or closed position enabling the control unit to switch from one position to the other.
Claims22
A mechanical actuating device for opening and closing at least one nozzle movable along a preset trajectory with respect to a support, comprising:
- at least one nozzle movable along a preset trajectory;
- a valve associated with each said at least one nozzle;
- said valve comprising a distributing element movable between an open position wherein a fluid can flow through said valve, and a closed position wherein said valve is sealed;
- and
- means for mechanically moving said distributing element between the open position and the closed position comprising at least one guide rail comprising a flexure for enabling said distributing element to move between the open position and the closed position.
A mechanical actuating device for opening and closing at least one nozzle movable along a preset trajectory with respect to a support, comprising:
- at least one nozzle movable along a preset trajectory;
- a valve associated with each of said at least one nozzle;
- said valve comprising a distributing element movable between an open position wherein a fluid can flow through said valve, and a closed position wherein said valve is sealed;
- and
- means for mechanically moving said distributing element between the open position and the closed position comprising two guide rails facing each other, each of said two guide rails comprising a flexure for enabling said distributing element to move between the open position and the closed position;
- and at least one roller swivel-mounted on said distributing element, and positioned for contacting said guide rails.
A mechanical actuating device for opening and closing at least one nozzle movable along a preset trajectory with respect to a support, comprising:
- at least one nozzle movable along a preset trajectory;
- a valve associated with each said at least one nozzle;
- said valve comprising a distributing element movable between an open position wherein a fluid can flow through said valve, and a closed position wherein said valve is sealed;
- and
- means for mechanically moving said distributing element between the open position and the closed position comprising two guide rails facing each other, each of said two guide rails comprising a flexure for enabling said distributing element to move between the open position and the closed position;
- intermediate operation means associated with said distributing element for contacting said two guide rails for moving said distributing element between the open position and the closed position;
- and at least one roller swivel-mounted on said intermediate operation means, and positioned for contacting said guide rails.
A spreading assembly, comprising:
- a mobile vehicle;
- a spreading rail on said mobile vehicle mounted for back and forth movement transverse to a displacement direction of said mobile vehicle;
- and
- a mechanical actuation device for opening and closing at least one nozzle movable along a preset trajectory with respect to a support, comprising:
- at least one nozzle movable along a preset trajectory;
- a valve associated with each said at least one nozzle;
- said valve comprising a distributing element movable between an open position wherein a fluid can flow through said valve, and a closed position wherein said valve is sealed;
- and
- means for mechanically moving said distributing element between the open position and the closed position comprising at least one guide rail comprising a flexure for enabling said distributing element to move between the open position and the closed position.
