TH3446B - Hydraulic fluid reservoir and reservoir - Google Patents

Abstract

OCR 13PL is a hydraulic fluid container (10, 110) specially adapted for connection to automotive hydraulic fluid reservoirs (40, 160) for the purpose of transferring fluid from the container to the reservoir. In one form, the supply pipe (30) has a specific cross-sectional shape that conforms to the opening (46) in the reservoir. In another form, valves (148, 150, 216,218, 316,318,416,418) in the container or reservoir are opened by fittings (164, 232, 332) located on the other part of the container and reservoir to connect the container and reservoir. This invention prevents fluid filling from the container and is not specially adapted for use with reservoir-to-reservoir applications.

Claims (4)

OCR 13PL 1. The arrangement of the automotive hydraulic fluid reservoir and container for transferring fluid to the reservoir consists of: - A reservoir opening; - A lid with a relatively restricted orifice located on the opening, which is removable; - A discharge port on the container, which has been adjusted to create a leak-proof male/female connection with the orifice on the lid. When connected to the reservoir, it allows fluid transfer from the container to the reservoir. The orifice on the lid has a valve pathway which is normally closed but can be opened when the opening on the container is connected. The discharge port on the container is connected to the orifice on the lid only when the cross-sectional shapes of the two parts are the same; - A locking mechanism to secure the lid and the discharge opening on the container; and - The lid also contains an opening to allow air to escape from the reservoir while fluid is being filled through the restricted orifice on the container and reservoir. 2. The automotive hydraulic fluid system of claim 1, where the orifice at the said cover is normally closed by the use of a counterweighted ball valve pathway against the orifice. 3. Methods for supplying hydraulic fluid to the automotive hydraulic fluid reservoir to minimize fluid contamination. These methods include: providing a reservoir with an inlet; providing a lid for the inlet with a relatively restricted orifice; providing a container with an outlet, which also has a relatively restricted orifice; the orifice of the lid and container may be connected in a leak-proof male/female relationship; locking the lid and container together when the orifice of the lid and container are connected in a leak-proof male/female relationship; and providing at least one opening in the lid to allow air in the reservoir to escape while the fluid is being filled through the restricted orifice in the container and reservoir. 4. The hydraulic fluid system of the vehicle of the first claim where such locking device includes the keyway and such opening includes wings that stand at least partially enclosing such opening. Such keyway includes the key body and such wings include adjustment openings for the key, positioned so that when rotated, the key body fits into the key slots on such wings, which, when this part is further rotated, results in the locking of the cover to the such opening.
