Aspects of the present invention relate to an apparatus comprising at least two chambers, each chamber comprising at least one wall defining the chamber, a fluid inlet and a fluid outlet through the wall of the chamber and an opening separate from the fluid inlet and fluid outlet. The fluid inlet and fluid outlet are configured such that a fluid enters the chamber via the fluid inlet and exits via the fluid outlet. A gas enters the chamber via the fluid inlet and exits the chamber via the opening, wherein the opening of each of the chambers is fluidly connected to a common fluid reservoir. The apparatus may be used for degassing multiple coolant circuits in a vehicle.

A reservoir for a vehicle is provided. The reservoir is accommodated in a body formed by joining an upper case and a lower case to each other. A high-pressure reservoir space introduces and discharges coolant flowing from a high pressure cooling line and a low-pressure reservoir space introduces and discharges coolant flowing from a low pressure cooling line. A valve is also installed to maintain internal pressure of the high-pressure reservoir space and the low-pressure reservoir space constant.

A cap (20) for a header box of a heat exchanger (1), in particular for a motor vehicle, in particular a radiator, is disclosed. This cap includes a head (21), a shank (22) comprising at least one mounting thread (23), this shank being between the head and a free end of the cap, a retaining lug (30), in particular elastically deformable, arranged to retain the cap in an opening (10) of the header box in an intermediate position of the cap, in which position the cap leaves a clear passage while being retained in the opening, this retaining lug being formed on the shank.

A safety cap (10), for a motor vehicle fluid reservoir (14), is configured to be attached and fixed to a neck (12) of the reservoir. The cap includes a screwing cover (16) with a first screw thread (16ba), and a safety cell (18) configured to allow passage of gas between the interior and the exterior of the reservoir, when the cap is fixed to the neck and when a pressure difference between the interior and the exterior of the reservoir is greater or less than at least one predetermined threshold value. The cap includes a ring (20) with structure (30, 30a, 32) for fixing to the neck and a second screw thread (22) to cooperate with the first screw thread. The cell is at least partly housed in the neck and surrounded by the cover and/or the ring when the cap is fixed on the neck.

A pressure cap for a cooling system of a vehicle may include a reservoir fill port which is mounted at an upper portion of a reservoir in which cooling water is stored in a cooling system of the vehicle; an external cap for closing an upper end portion of the reservoir fill port; a pressure valve disposed in the reservoir fill port to allow the inside and the outside of the reservoir fill portion to fluidically-communicate with each other; a valve seal provided to allow the air to flow from the outside into the internal to the cooling system by being deformed when pressure in the internal to the cooling system is lower than a predetermined pressure; and a positive pressure spring elastically supporting the pressure valve such that the pressure valve closes the internal to the reservoir fill port.

A cap for a coolant reservoir that accommodates the expansion of coolant stored therein. The expanding coolant results from an increase in temperature and causes an increase in pressure to build within the coolant reservoir. The cap includes a base and a crown having an air-dome which extends upwardly therefrom. The base includes a passageway extending therethrough and in fluid communication with an interior cavity or an air gap formed in the crown. As the cap is positioned over an open neck of the coolant reservoir, by being screwed or otherwise fitted thereon, the interior cavity remains positioned above the neck. Thus, as the coolant within the coolant reservoir becomes heated and expands, the interior cavity provides additional space for the coolant to occupy and pressure to build within.

An installation structure for a reservoir tank includes a main frame that extends rearward from a head pipe, a down frame that extends downward from the head pipe, a bridge that connects the down frame and the main frame, a radiator disposed in front of the engine and configured to radiate heat from cooling water of an engine, and a reservoir tank configured to adjust a flow rate of cooling water in the radiator. The reservoir tank is provided above the engine and rearward of the radiator so as to overlap a region surrounded by the main frame, the down frame, and the bridge in a side view.
