Abstract
A fluid delivery device, in particular for the delivery of combustion air to a heating burner of a motor vehicle or for the delivery of heating medium, preferably heating air, through a heating medium duct system of a motor vehicle, comprises a delivery member which can be driven to rotate by a drive, a rotary state monitoring arrangement for monitoring the rotary state of the delivery member, and also an operating state sensing arrangement for determining the operating state of a system to be supplied with fluid by the fluid delivery device, based on the monitoring result of the rotary state monitoring arrangement.
Claims21
A fluid delivery device, comprising:
- a delivery member (18) that can be driven to rotate by a drive (16),
- a rotary state monitoring arrangement (34, 40) for monitoring a rotary state of the delivery member (18), and
- an operating state sensing arrangement (40) for determining an operating state of a system (10) to be supplied with fluid by the fluid delivery device, based on a monitoring result of the rotary state monitoring arrangement (40).
A process for characterization of an operating state of a system (10) to be supplied with a fluid by a fluid delivery device (12), wherein the fluid delivery device (12) comprises a delivery member (18) which can be driven to rotate, comprising the steps of:
- (a) producing a rpm quantity reproducing an rpm of the delivery member (18),
- (b) monitoring the rpm quantity,
- (c) based on the rpm quantity or on a therewith connected control quantity for a drive (16) with the delivery member (18), recovering information characterizing the operating state of the system.
