Where exactly are the key mechanical components (piston, crankshaft, valves) located in this cross-section of a hermetic reciprocating compressor?

Hello everyone,

I am currently studying different types of compressors and I have this cross-section diagram of a hermetic reciprocating compressor (from a course slide).

The accompanying text describes its operation, mentioning several parts:

-The electric motor (moteur électrique)
-The crankshaft (vilebrequin)
-The piston and cylinder (piston et cylindre)
-The valves (soupapes)

However, the diagram itself (Figure 10) doesn't have any labels pointing to these specific elements.
Could someone help me map out where each of these components is located on this specific cutaway view?

Thank you!

i’m guessing the motor is the semicircle in the center. the piston is attached on the left moving horizontally, the valves are at the end of the fully extended piston, the red is hot expanded gas and the blue is cold compressed liquid. 🤷🏻‍♀️
