Dynamic Mesh - Compression

I'm working on a compression problem by using dynamic mesh. I solved my previous problems with CFD Online and now i have a big mistake. Problem scheme is presented in figure1. Pressure inlet condition is 0.5 bar absolute pressure. In valve opens at 45° of crank angle. Cylinder diameter is 25mm and connecting rod length is 47mm. While piston is going to TDC before opening the inlet valve 40° diagramme is could be seen in figure 2 and 3. In pressure diagramme, the compression chambers pressure is -80 bar . I use pressure based solver and coupled pressure-velocity coupling scheme, standart pressure and default under relaxation factors. -80 bar is impossible so what is my mistake?
Thanks in advance, best regards.
