Abstract
A valve with an inlet, an outlet that is connected to the inlet via a fluid connection, and a valve body which can be brought by displacing it along a displacement direction into a first position, in which the fluid connection is blocked, and a second position, in which the fluid connection is open, wherein the inlet is designed and arranged in such a way that a fluid entering through the inlet exerts a total force on the valve body that at least also acts in a force direction which is perpendicular to the displacement direction when the valve body is in the first position.
Claims12
A valve comprising:
- an inlet;
- an outlet that is connected to the inlet via a fluid connection;
- and
- a valve body movable along a displacement direction into a first position, in which the fluid connection is blocked, and a second position, in which the fluid connection is open;
- a spring positioned above the valve body, wherein the spring spring-loads the valve body towards the first position,
- a switch spring, which is configured to transfer a force from a switch pin to the valve body when the switch pin is activated,
- wherein the valve body is maintained in the second position when a fluid is flowing in the fluid connection, a pressure of the fluid is greater than a predetermined limit;
- and the flowing fluid and the pressure of the fluid maintain the valve body in the second position.
A valve comprising:
- an inlet;
- an outlet that is connected to the inlet via a fluid connection;
- a connection channel fluidly connected to the outlet;
- a valve body movable along a displacement direction into a first position, in which the fluid connection is blocked, and a second position, in which the fluid connection is open;
- a switch spring, which is configured to transfer a force from a switch pin to the valve body when the switch pin is activated,
- wherein the connection channel generates a negative pressure that maintains the valve body in the second position when the fluid is flowing in the fluid connection, a pressure of the fluid is greater than a predetermined limit, and the flowing fluid, the negative pressure, and the pressure of the fluid maintain the valve body in the second position, wherein the valve comprises a switch spring, which is configured to transfer a force from a switch pin to the valve body when the switch pin is activated.
