  • Publication number: 20230168008
    Abstract: A thermal management system includes a refrigerant loop including a compressor, a condenser, an expansion element, and a chiller. A first coolant loop of the thermal management system includes the chiller, a first cooling heat exchanger disposed downstream of the chiller, and a distribution valve disposed downstream of the first cooling heat exchanger. A coolant flow path branches from the first coolant loop with the coolant flow path extending from the distribution valve to a re-entry point where the coolant flow path rejoins the first coolant loop at a position downstream of the distribution valve. The coolant flow path includes an electric component, and the distribution valve is configured to control a distribution of the first coolant flowing towards the electric component and the re-entry point.

  • Patent number: 11664545
    Abstract: A charging system includes an electric vehicle having a battery coolant circuit including a charging heat exchanger and a battery as well as a charging station including a charging coolant and a cooling heat exchanger for cooling the charging coolant. The charging coolant is selectively placed in fluid communication and heat exchange communication with the charging heat exchanger of the electric vehicle. The charging heat exchanger is disposed on a charging coolant flow path formed in the electric vehicle that extends from an inlet port configured for coupling to an inlet fitting of the charging station to an outlet port configured for coupling to an outlet fitting of the charging station.

  • Patent number: 5638944
    Abstract: An anti-theft sensor contact mechanism for an ignition system of an automotive vehicle has a sensor contact mechanism 24 which utilizes a non-conducting lever 46 to sense the physical presence of a lock liner 26 within a lock cylinder 28 of the ignition system and to depress a moveable contact 40 against a stationary contact 38 of the same metal for closing a path in an electrical monitoring, or sensing, circuit 32. When the lock liner 26 is removed, such as when tampered with during theft of the vehicle, the sensor contact mechanism 24 causes a break in an electrical path in the circuit 32 through movement of the moveable contact 40 to a non-contacting position with the stationary contact 38 so that a conventional alarm system may be triggered to sound an audible or visible.

  • Patent number: 4243535
    Abstract: A filter assembly comprises a plurality of filter elements telescopically mounted relative to each other and in a housing defining an inlet and an outlet thereon. Each filter element comprises a tubular screen having a plurality of longitudinally extending ribs secured in circumferentially spaced relationship therearound. First and second filter elements of each radially adjacent pair of filter elements have the ribs thereof aligned in abutting relationship to space the screens of the filter elements radially from each other to define a flow passage therebetween. The screen of the outermost filter element is cylindrical, the screen of the next radially adjacent filter element is frustoconically shaped and et sequence to closely compact the filter elements together. An end cap is secured on one end of the filter assembly to retain it in place in the housing.
