A fluid supply system with a component includes a first bypass valve arranged in a control channel with a valve body adjustable at least between a first and a second position. The valve body separates the control channel into a first and a second space and has a leakage opening connecting the first space to the second space. The second space is connected to a fluid reservoir via a leakage channel, and a switchable valve is arranged in the leakage channel. A sensing device is configured to sense a property of the fluid and convey the property to a controlling device that is configured to close the valve to block the leakage channel when a predefined property is reached. A second bypass valve is configured to reduce a transient oscillation of the first bypass valve during a starting of the system.

Fluid supply system

The invention relates to a liquid filter, having a filter housing, which contains a receiving space for a ring filter element. The liquid filter further has a no-load duct, which is opened when the ring filter element is taken out. A pin is formed on a lower end disc of the ring filter element, the pin projects parallel to the longitudinal axis. A ramp is formed on the bottom of the receiving space. The ramp is matched to the pin in such a manner that, when the ring filter element is inserted into the filter housing, the pin slides downwards on the ramp and penetrates the opening of the no-load duct. A structure is in the receiving space, the structure allows functional insertion of the ring filter element if the ring filter element slides with its pin along the ramp until the pin penetrates the opening of the no-load duct.

Liquid filter, in particular an oil filter

The present invention relates to a cooling mechanism (), in particular for cooling oil in a motor vehicle, with a housing () having a bracket (), by means of which housing () the cooling mechanism () is connected to an internal combustion engine, a transmission fluid cooler (), and an engine oil cooler (). Pertinent to the invention is that the cooling mechanism () is designed in a sandwich-type manner having an intermediate module () positioned between the engine oil cooler () and the transmission fluid cooler (), which intermediate module () has at least one supply/removal assembly () that communicates with the engine oil cooler () and has corresponding supply/removal lines or connections.
