Abstract
The invention refers to a valve, in particular a pneumatic valve with a tappet or nipple provided on an actuator member that opens or closes a passage opening for a medium depending on the position of the actuator. A tappet is provided the spring of that presses the tappet or nipple on the passage opening in the closed position.
Claims18
A valve comprising:
- a body with a passage opening for a medium;
- an actuator having a recess;
- a tappet, having first and second ends, disposed with clearance within the actuator recess and configured for linear movement within the recess;
- a longitudinally movable operating body serving as a hand key;
- a readjusting spring;
- and
- a tappet spring, supported in the longitudinally movable operating body, in direct, linear mechanical cooperation with the first end of the tappet, the tappet spring configured to bias the second end of the tappet towards the passage opening,
- wherein the tappet is in a closed position, on the passage opening, when the actuator is in a first position and the tappet is in an open position, spaced from the passage opening, when the actuator is in a second position, and
- wherein the operating body acts against the power of the readjusting spring, via the tappet spring, on the tappet and the actuator, respectively.
6 more elements
A valve, comprising:
- a housing with a valve space defined therein;
- a solenoid disposed in the housing;
- a web structure disposed in the valve space;
- a hinged armature positioned to swivel on the web structure, the armature having first and second ends and a respective recess in each end;
- first and second tappets disposed with clearance, respectively, in the first end recess and the second end recess of the armature, each of the first and second tappets having first and second ends and configured for linear movement within the respective recess;
- first and second passage openings disposed, respectively, adjacent to the first and second tappets;
- a first tappet spring provided in the housing in direct, linear mechanical cooperation with the first end of the first tappet and configured to urge the first tappet toward the first passage opening;
- and
- a second tappet spring provided in the housing in direct, linear mechanical cooperation with the first end of the second tappet and configured to urge the second tappet toward the second passage opening,
- a longitudinally movable operating body serving as a hand key provided in the housing;
- and
- a readjusting spring provided in the housing and arranged in cooperation with the moveable operating body,
- wherein the second tappet spring is supported in the longitudinally movable operating body,
- wherein the moveable operating body acts against the power of the readjusting spring, via the second tappet spring, on the tappet and the armature, respectively,
- wherein, in a first state of operation when the solenoid is inactive, the first tappet spring directly urges the first tappet to close the first passage opening and the second passage opening is open and fluidly coupled with the valve space, and
- wherein, in a second state of operation when the solenoid is active, the armature is attracted to the solenoid and the first tappet is removed from the first passage opening to fluidly couple the first passage opening with the valve space and the second tappet spring directly urges the second tappet to close the second passage opening.
