Abstract: A centrifugal coolant gas separator (CCGS) for a cooling system is provided. In one example configuration, the CCGS includes a main body defining a cyclone separator chamber therein configured to separate a flow of coolant into gas and liquid coolant, a liquid outlet formed in the main body and configured to receive the separated liquid coolant from the cyclone separator chamber, and a gas outlet formed in the main body and configured to receive the separated gas from the cyclone separator chamber. A first inlet is configured to receive a forced flow of a first portion of a coolant flow, and a second inlet is configured to receive a second portion of the coolant flow. The forced first portion of coolant flow induces the second portion of coolant flow into the cyclone separator chamber for subsequent gas and liquid coolant separation of the first and second portions of coolant flow.

Abstract: A liquid drain valve assembly for a charge air cooler includes a valve housing configured to couple to the charge air cooler, the valve housing having a condensate inlet configured to receive condensate from the charge air cooler, and a condensate outlet, a valve mechanism slidingly disposed within the valve housing and configured to selectively close the condensate inlet and the condensate outlet to facilitate preventing charge air from leaking during condensate draining, and a diaphragm assembly disposed within the valve housing and configured to selectively engage the valve mechanism to selectively open the condensate inlet and the condensate outlet to drain condensate from the charge air cooler when the charge air cooler is in a boosted condition and isolated from the atmosphere.
