Modern vehicles include heating, ventilation, and air conditioning (HVAC) systems for improving passenger comfort.
In general, vehicle air conditioning systems include an evaporator heat exchanger in communication with a compressor and a condenser. A compressor receives heated refrigerant from the evaporator and compresses it into a high pressure gas for communication to the condenser. The condenser then cools the gaseous refrigerant into a cool liquid refrigerant for communication back to the evaporator. A blower forces air across the evaporator, providing cooled air into the engine compartment.
A vehicle heating system includes a heater core that receives hot engine coolant from the engine. A blower forces air across the heater core, providing heated air to the passenger compartment.
Advancements in the field of vehicle HVAC system design and manufacturing are desirable.

The drawings can be briefly described as follows:
The evaporator core 18 communicates heated refrigerant gas to the compressor 22, which compresses the refrigerant into a high pressure gas to be communicated to the condenser 23. The condenser 23 condenses the refrigerant into a cooled liquid refrigerant for communication back to the evaporator 18.
The heater core 20 is in communication with the engine 25 for communicating heated liquid to the heater core 20 and cool liquid back to the engine 25. The compressor 22, condenser 23, and engine 25 are located in the engine bay area 14.
The HVAC system 12 may include one or more actuator assemblies M for opening and closing doors (i.e., valves) that are internal to the module 16 to control airflow, such as the flow of fluid across evaporator 18 and/or heater core 20 and/or flow to specific areas of the vehicle cabin area 15. An example of such an actuator assembly 24 is illustrated in
The actuator retainer 30 includes, in this example, three mounting flanges 32, 34, 36 (
The retainer 30 includes an actuator retention platform 38 between the mounting flanges 32, 34, 36. In this example, the retention platform 38 is elevated, in the direction D1, relative to the mounting flanges 32, 34, 36. In the example, when the retainer 30 is mounted, the direction D1 is substantially horizontal. Further, the retention platform 38 includes an upper surface 40, which is relatively planar, and is configured to directly contact a lowermost surface of the actuator 28. In this example, a pair of latches 42, 44 extend upward from the upper surface 40. A locating projection 46 may also extend upward from the upper surface 40. In one example, when the retainer 30 is mounted, the platform 38 extends along a vertically oriented plane (see
In this example, the actuator 28 has three mounting openings 48, 50, 52. As illustrated in
The latches 42, 44 engage respective platforms 52, 54 formed in the upper surface of the actuator 28 to retain the actuator 28 against the retainer 30 in the direction D1. The latches 42, 44 also limit movement of the actuator 28 in the directions D2. In this example, movement of the actuator 28 relative to the retainer 30 in the directions D2 is further restricted by another projection 56, which projects upwardly from the upper surface 40 and is arranged generally on an opposite side of the actuator 28 as the projection 46. The projection 56 is not required in all examples. Alternatively, more than one additional projection 56 may be used.
The latches 42, 44 in the example are located opposite the actuator 28 from one another, but other orientations are contemplated. For example, as shown in
This disclosure provides an effective actuator retainer that does not require fasteners between the actuator 28 and the retainer 30. The snap fitting created by the latches 42, 44 does not require any fasteners for actuator retention. Since no fasteners are required, assembly time is reduced.
Although the different examples have the specific components shown in the illustrations, embodiments of this disclosure are not limited to those particular combinations. It is possible to use some of the components or features from one of the examples in combination with features or components from another one of the examples.
One of ordinary skill in this art would understand that the above-described embodiments are exemplary and non-limiting. That is, modifications of this disclosure would come within the scope of the claims. Accordingly, the following claims should be studied to determine their true scope and content.
