A transmission includes an oil sump and at least one oil bunker arranged separated from the oil sump within the transmission. The transmission includes a valve having a channel body, at least one sump port, at least one bunker port, and a mechanical actuating element. The channel body has at least one oil duct. The at least one oil duct connects the at least one bunker port to the at least one sump port. The mechanical actuating element is configured for temperature-dependently deforming to transfer the valve out of a closed position into at least one open position. The at least one oil bunker is connected to the oil sump via the valve when the valve is in the at least one open state. The at least one oil bunker is not connected to the oil sump via the valve when the valve is in the closed state.

Apparatuses described herein relate to improving the shape morphing of structures using bistable cells. In one embodiment, an inflatable structure comprises an inflatable membrane with an inner top surface and an inner bottom surface opposite the inner top surface. The inflatable structure further comprises an array of vertically stacked bistable cells with a first end attached to the inner top surface and a second end attached to the inner bottom surface, where each of the bistable cells of the array is configured to change from a first state to a second state according to a change in pressure within the inflatable membrane.
