The motor includes a sealing material (dry body of a liquid gasket 41) interposed between a joint surface 3b of a motor housing 3 and a joint surface of an inverter housing, and an O-ring 39. The O-ring 39 is interposed between the motor housing 3 and the inverter housing and disposed so as to surround the communication port 3a1 of the refrigerant flow path 3a. The motor housing 3 includes a groove 3d disposed between the sealing material and the O-ring 39 on the joint surface 3b in a surface direction of the joint surface 3b.

A seal assembly and methods of use, wherein the seal assembly is formed of an elastomeric enclosure within which a primary cavity is defined. A second cavity in the form of a crushable container is deployed within the primary chamber. An elastomeric compound is contained in one cavity and an elastomeric hardener contained in the other cavity. Upon application of an external force to the elastomeric enclosure, the enclosure is elastically deformed from a first shape to a second shape, wherein the second shape positions the elastomeric enclosure into a sealing configuration between adjacent annular surfaces. The external force also crushes the container, to cause mixing of the elastomeric compound and elastomeric hardener. Once the reaction is complete, the hardened compound retains the deformed shape of the elastomeric enclosure to maintain a seal between the annular surfaces.

A case, a battery, a power consuming device, and a method for assembling a case are provided. The case includes a first case body, an accommodating groove, a sealant, and a second case body. The first case body is provided with an opening. The accommodating groove is provided in a peripheral direction of the opening. The sealant is accommodated in the accommodating groove. The second case body is provided with a peripherally-arranged joint part. The joint part is configured to extend into the accommodating groove and be joined with the sealant when the second case body covers the opening, so as to form a sealed connection between the first case body and the second case body. The accommodating groove can limit the sealant, the sealant does not shift in the accommodating groove, and a sealing failure is less likely to occur, thus ensuring the sealing performance of the sealant.
