Pneumatic symbols

[dejan95]

Hello engineers,

Could you help me explain this pneumatic symbol:

I would wish to know what exactly are this three marked things:

I know there is solenoid but I'm not exactly sure what the other symbols are and how this valve operates?

For example here is similar one, but without dolenoid on the right side...

Been a very long time since I worked with solenoids. Maybe it indicates some type of spring?
