Drawing in LaTeX

Question

I really like Tikz for drawing little and easy diagrams in my LaTex documents. However, I am not very skilled so I'm looking for someone to give me a help to realize this drawing (without colors: D). Thank you all for the help!

Answer 1

Since you are a beginner and I had some time to kill, I am going to provide you with a very basic starting point for your diagram. Actually, it replicates the diagram fairly well. You could play around with this and the PGF manual.

Hope you tikz more and help others in future in LaTeX Stack Exchange.

Answer 2

Thank you so much anakrich! I hadn't posted any code because I didn't know how to start XD I tried to play with your code to get something more stylish :P Here is the modified code:

\begin{tikzpicture}[scale=1]

% Cylinder
\begin{scope}[fill=teal!20]
    \fill[draw, rounded corners=2mm] (0,0) rectangle (2,3);
    \fill (1.9,1.25) rectangle (3,1.5)
    (3,1) rectangle (3.75,1.75)
    (3.75,1.75) rectangle (7,0.5);
    \node [shape=isosceles triangle, fill=black,rotate=90,scale=0.3] at (2.5,1.25){};
    \node [shape=isosceles triangle, fill=black,rotate=-90,scale=0.3] at (2.5,1.5){};
\end{scope}

% Cylinder Boundary 
\draw[thick] (2,1.25) -- (3,1.25);
\draw[thick] (3,1.25) -- (3,1);
\draw[thick] (3,1) -- (3.75,1);
\draw[thick] (3.75,1) -- (3.75,0.5);
\draw[thick] (3.75,0.5) -- (6.98,0.5);
\draw[thick] (6.98,0.5) -- (6.98,0.6);
\draw[thick] (6.98,1.65) -- (6.98,1.75);
\draw[thick] (6.98,1.75) -- (3,1.75);
\draw[thick] (3,1.75) -- (3,1.5);
\draw[thick] (3,1.5) -- (2,1.5);

% Piston
\begin{scope}[fill=gray!60]
    \fill (3.1,1.1) rectangle (4.1,1.65);
    \fill (3.85,1.65) rectangle (7.0,0.6);
    \fill (7,1) rectangle (8,1.25);
\end{scope}

% Piston Boundary   
\draw[thick] (7,1) -- (8, 1);   
\draw[thick] (7,1.25) -- (8, 1.25);
\draw[thick] (3.85,0.6) -- (7, 0.6);
\draw[thick] (7,0.6) -- (7, 1);
\draw[thick] (7,1.25) -- (7, 1.65);
\draw[thick] (3.1,1.65) -- (7, 1.65);
\draw[thick] (3.1,1.65) -- (3.1, 1.1);
\draw[thick] (3.1,1.1) -- (3.85, 1.1);
\draw[thick] (3.85,1.1) -- (3.85, 0.6);

% Sled
\fill [yellow] (8,0.75) rectangle (10,1.5);
\fill [black]
(8.4,0.6) circle (0.15)
(8.7,0.6) circle (0.15)
(9.3,0.6) circle (0.15)
(9.6,0.6) circle (0.15);
\draw[thick] (10,1.2) .. controls (10.25,1.2) and (10.25,2) .. (10.5,2);

% Sled Boundary
\draw[thick] (8,0.75) -- (10,0.75);
\draw[thick] (10,0.75) -- (10, 1.5);
\draw[thick] (8,1.5) -- (10,1.5);
\draw[thick] (8,0.75) -- (8, 1.5);

% Ground
\draw[thick] (8,0.45) -- (10,0.45);
\fill [pattern = north east lines] (8,0.25) rectangle (10,0.45);

% Text
\node [align=center,anchor=north] at (1,0) {Serbatoio ad\\aria compressa};
%\node [anchor=north] at (2.75,0) {Valvola};
\node [align=center,anchor=north] at (5.3,0) {Sistema cilindro - pistone\\con sezione a scalino};
\node [align=center,anchor=north] at (9,0) {Slitta di\\alaggio};
\node[red] at (2.85,2) {Pressione};
\node[red] at (6.75,2) {Contro-Pressione};
\node [align=center] at (9.75,2.5) {Cavo di\\traino};

% Arrows
\foreach \y in {0.7,0.9,1.35,1.55}
\draw[thick, red,<-] (7,\y) -- (7.5,\y);
\foreach \y in {1.15, 1.35, 1.55}
\draw[thick, red,->] (2.75,\y) -- (3.1,\y);
\draw [thick, red,->] (2.75,0.95) .. controls (3.5,1) and (3,0.7) .. (3.85,0.7);
\end{tikzpicture}

Again, thank you so much !!!
