In a reservoir assembly for a tandem master cylinder of a hydraulic braking system the container is separated into compartments by at least one baffle passages being provided for permitting limited communication between the compartments past the baffle. The arrangement is such that when the container is installed in a vehicle and the brakes are applied, the tendency of fluid to transfer from one compartment to another is resisted. The arrangement also ensures that even under the worst conditions of deceleration and altitude of the vehicle there will be a sufficient volume of fluid in the compartments to cover outlets to the master cylinder and thus sustain subsequent brake application.

Reservoir assemblies for vehicle braking systems

In a reservoir comprising a container for liquid at least one portion of the top wall of the container is depressed to form a window, the depressed portion and at least a part of the surrounding area being transparent or translucent so that the reservoir can be filled with a liquid until the liquid is in visible contact on the under surface of the window with the surrounding part untouched.

Reservoirs for liquids

Liquid reservoir primarily for use in a vehicle braking system

An hydraulic reservoir for a dual circuit braking system of the kind comprising a container divided into two chambers by a partition provided with a hole at an intermediate height, and a fluid level sensor located in one chamber, in which the chambers are sealed from each other in use apart from the hole in the partition, and one of the chambers is sealed against atmosphere by sealing means which can be released to allow leveling of the fluid during filling.

Hydraulic reservoirs for vehicle braking systems

In a tandem master cylinder main and secondary pistons are interconnected by a rigid sleeve. One end of the sleeve is secured to one of the pistons, and an inwardly projecting lip or flange on the other end of the sleeve provides an abutment for a head on an axial stem extending from the other piston towards the said one piston. The head is axially slidable in the sleeve and is introduced into it through an opening in the wall of the sleeve, which opening is connected by a longitudinal slot to the end of the sleeve which is provided with the lip or flange.
