Abstract
A valve apparatus, in particular for a cooling system of a vehicle, includes a housing having at least two fluid connectors, a valve device which can be adjusted at least between a first valve position and a second valve position, and a drive for adjusting the valve device between the first valve position and the second valve position. The valve apparatus includes a fail-safe adjustment device in order to transfer the valve device from the first valve position into the second valve position in the event of an incident in which the power supply, in particular that of the vehicle, is interrupted.
Claims17
A rotary valve apparatus, comprising
- a housing having at least two fluid connectors,
- a valve device rotatable at least between a first valve position and a second valve position, and
- a drive for rotating the valve device between the first valve position and the second valve position,
- wherein a fail-safe adjustment device is provided in order to rotate the valve device from the first valve position into the second valve position in the event of an incident;
- wherein the fail-safe adjustment device comprises a fail-safe electrical power source for powering the drive to at least partially rotate the valve device from the first valve position to the second valve position.
A rotary valve apparatus, comprising
- a housing having at least two fluid connectors,
- a valve device rotatable at least between a first valve position and a second valve position, and
- a drive for rotating the valve device between the first valve position and the second valve position,
- a fail-safe adjustment device for rotating the valve device from the first valve position into the second valve position in the event of an incident;
- wherein the fail-safe adjustment device comprises a first gear driven by a second gear, the second gear is geared for rotation by the drive, wherein the first gear is configured such that, during operation of the fail-safe adjustment device, the first gear is initially rotated by the second gear to rotate the valve device toward the second valve position, and the first gear then separates from the second gear.
A valve apparatus, comprising
- a housing having at least two fluid connectors,
- a valve device adjustable at least between a first valve position and a second valve position, and
- a drive for adjusting the valve device between the first valve position and the second valve position,
- a fail-safe adjustment device having an eccentric element that is rotatable in order to adjust the valve device from the first valve position into the second valve position in the event of an incident;
- wherein the fail-safe adjustment device comprises a fail-safe electric power source for powering the drive to rotate of the eccentric element in a direction to adjust the valve device toward the second valve position, and an axial spring device that interacts with the eccentric element to translate linear movement of the axial spring device into rotary movement of the eccentric element so as to adjust the valve device.
