A storage tank for storing a liquid comprises a main storage chamber; an internal sub chamber located within the storage tank; and a reclosable filling opening for enabling filling of liquid into the main storage chamber and internal sub chamber. An overflow level of the internal sub chamber is located substantially at or above a predetermined fill level of the main storage chamber. The reclosable filling opening and the internal sub chamber are arranged in a substantially superposed relationship in a vertical direction, such that a substantially or entirely vertical stream of liquid filling the storage tank via the reclosable filling opening is configured to enter the internal sub chamber. A method for filling a storage tank with a liquid, a method for manufacturing a storage tank for storing a liquid, and a system comprising a storage tank and a filling nozzle are also described.

Systems and methods disclosed provide an automotive fluids management and maintenance system (AFMMS) that manages and maintains fluids within vehicles by accurately and in a controlled manner directing the propulsion of these fluids into vehicle's internal components and also accurately and in a controlled manner draining fluids out of vehicle's internal components. The systems and methods enable a technician to dispense any desired fluid and pump the same into a vehicle internal component with speed, efficiency, accuracy, and in a very clean and unwasteful manner. The AFMMS is powered by a standard shop air supply. Once charged with air pressure, the AFMMS becomes mobile and is without any attachments, e.g., to a wall air supply, thus making it safe and convenient to be used around any shop environment, as well as outside in parking lots.

A method for filling a hydraulic system with a hydraulic fluid includes sealing the hydraulic system in a pressure-tight manner and recording a pressure in the sealed hydraulic system, filling or removing a predefined volume of the hydraulic fluid from the sealed hydraulic system, recording a pressure in the sealed hydraulic system after the filling or removing, calculating a volume of a total residual air in the hydraulic system depending on the pressures before and after the filling or removal of the predefined volume, calculating a final correction volume depending on the volume and a design-specified air feed of the hydraulic system, and refilling or removing the calculated final correction volume to achieve a final correct filling quantity for the hydraulic system.

A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose packet, electrical, pneumatic, and hydraulic lines. A filling adapter according to the disclosure achieves better fluid flow properties while reducing the overall size, production costs, and weight of the filling adapter. The filling adapter is equipped with a coaxial valve in the region of the adapter head of the filling adapter, which coaxial valve, starting from the inlet cross section, is initially provided with a flow contour extending parallel to the longitudinal axis of the valve, which in the further flow course transitions into a flow contour extending at a right angle to the longitudinal axis of the valve to the outlet cross section.

A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose pack, electrical, pneumatic, and hydraulic lines. An interface is configured for coupling a gripping element designed as a separate assembly on the filling adapter in the region of the adapter head, wherein the interface has mechanical and electrical connecting elements which are disposed in a common plane and can be coupled to mechanical and electrical connecting elements of the gripping element which are congruent therewith.

A cooler apparatus includes: a coolant passageway; a water pump that circulates coolant in the coolant passageway; a thermostat that includes a heater that heats a temperature sensitive portion; and a controller. The controller is configured to drive the water pump and cause electric current to flow through the heater at a first energization amount when an operation in which the coolant is injected into the coolant passageway is started. The controller is also configured to stop electric current to flow through the heater if the water pump races when the electric current flows through the heater at the first energization amount.

A system for vacuum filling a cooling assembly is provided. The system comprising a manifold comprising a first aperture, a second aperture, and a third aperture. Further, an eductor fluidly coupled to the first aperture, a first valve fluidly coupled between the eductor and the first aperture, and an expansion reservoir sealingly coupled to the second aperture. An end unit is fluidly coupled to the third aperture, the end unit comprising a conduit fluidly coupled with the third aperture, a second valve fluidly coupled to the conduit, a cap for sealingly coupling with a supply volume, and a pipe coupled to the cap and fluidly coupled with the conduit, the pipe sealingly coupled to the cap and extending outwardly from the cap.

A fluid exchanger may exchange a fluid (e.g., coolant) in a reservoir (e.g., vehicle radiator) by removing or withdrawing a first fluid (e.g., old, spent, used, etc.) and by introducing a second fluid (e.g., new, clean, etc.). In some examples, the exchanger includes a valve construction that permits easy and safe transitioning from a first mode in which the fluid in the vehicle is run in a loop (e.g., after a cleaner is introduced) to a second mode in which the fluid is exchanged. In some examples, the exchanger includes a restrictor that stops fluid from flowing when the pressure fails to satisfy a threshold (e.g., where the pressure is below a threshold). In some examples, the exchanger includes a safety valve (e.g., ball valve) in the bottom of the new fluid tank, such that when the tank is empty, the valve will close and reduce the likelihood of unintentionally pushing air into the system (e.g., emptying the reservoir).
