Abstract
The present invention discloses a valve assembly for controlling a differential pressure, including a housing, an actuating device, a first, a second, and a third port, a first sealing seat, a second sealing seat, and a valve member whose interaction with the first sealing seat controls a first connection between the first and the second port, and whose interaction with the second sealing seat controls a second connection between the second and the third port. In order to ensure an optimal analog controllability, according to the present invention, the sealing seats are axially opposite each other and have equal effective diameters, and the valve member is arranged between the sealing seats.
Claims10
A valve assembly for controlling a differential pressure, comprising:
- a valve housing,
- an actuating device disposed within the valve housing,
- an actuating element movable into engagement with the actuating device,
- a first resiliently biased sleeve slidable in the valve housing and including a first sealing seat,
- a second resiliently biased sleeve slidable in the valve housing and including a second sealing seat, the second sealing seat arranged axially opposite the first sealing seat, and
- a valve member stationarily arranged in the valve housing between the first and second sealing seats, the first sealing seat interacting with the valve member to control a first connection between a first port and a second port, the second sealing seat interacting with the valve member to control a second connection between the second port and a third port,
- wherein one of the first and second sealing seats engages the actuating element and is separated from the valve member when the valve assembly is in an inactive position, and wherein the other one of the first and second sealing seats engages the actuating element and is separated from the valve member when the valve assembly is in an active position,
- wherein the actuating element is of a bowl-shaped configuration including a first outward area and a second outward area, and wherein the first sleeve includes a first collar opposite the first sealing seat and a second collar opposite the second sealing seat.
