How does our pcv valves work???

My understanding how does a pcv valve work if it has no line or hose running to it if its under the plate,I didnt even know one was there,thought it was a plate were one could be,so I changed mine today and it was dirty,usually they go into the valve cover,how do they work on the sc?

It is routed internally through the motor instead of externally like you see on some applications.
