Abstract
Official abstract text for this publication.
A fluid arrangement for fluid actuation of at least one clutch and at least one transmission component and including a fluid energy source. The fluid energy source is a fluid pump including a first transport direction, in which the fluid pump serves on a transmission side to actuate the transmission component, and including a second transport direction opposite to the first transport direction, in which the fluid pump serves on a clutch side to actuate the clutch.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluid arrangement comprising: a reversible pump; a transmission actuator; a transmission hydraulic line connecting the reversible pump to the transmission actuator; a clutch actuator; a clutch hydraulic line connecting the reversible pump to the clutch actuator a first connecting line connecting the transmission hydraulic line to a fluid reservoir; a second connecting line connecting the transmission hydraulic line to the fluid reservoir; and, a dual pressure valve hydraulically connected to the first connecting line, the second connecting line, and the reservoir, wherein: the dual pressure valve comprises: a first control cylinder hydraulically connected to the first connecting line; and, a second control cylinder hydraulically connected to the second connecting line; the first control cylinder is arranged to connect the second connecting line to the fluid reservoir when operated on by a pressure in the first connecting line; and, the second control cylinder is arranged to connect the first connecting line to the fluid reservoir when operated on by a pressure in the second connecting line. 2. The fluid arrangement of claim 1 further comprising a hydraulic medium, wherein the reversible pump is configured such that: rotation of the reversible pump in a first rotational direction pressurizes the hydraulic medium to actuate the transmission actuator; and, rotation of the reversible pump in a second rotational direction, opposite to the first rotational direction, pressurizes the hydraulic medium to actuate the clutch actuator.
