Find all integers  $ (x,y,z)$, satisfying equality: 
$ x^2(y \minus{} z) \plus{} y^2(z \minus{} x) \plus{} z^2(x \minus{} y) \equal{} 2$
To find all integer solutions \((x, y, z)\) that satisfy the equation:
\[ x^2(y - z) + y^2(z - x) + z^2(x - y) = 2, \]
we will proceed by analyzing different cases based on the relative values of \(x, y,\) and \(z\).

1. **Assume \(x \geq y \geq z\) or \(z \geq y \geq x\):**
   - Rearrange the given equation:
     \[ x^2(y - z) + y^2(z - x) + z^2(x - y) = 2. \]
   - We can rewrite it as:
     \[ xz(z - x) + y(x^2 - z^2) = 2 + y^2(x - z). \]
   - Since \(x - z = 0\) leads to a contradiction (as it would make the denominator zero), we divide by \(x - z\):
     \[ y(x + z) - xz = \frac{2}{x - z} + y^2. \]

2. **Case \(x \geq y \geq z\):**
   - Consider \(x - z = 1\) or \(x - z = 2\).

3. **Subcase \(x - z = 1\):**
   - **Case 1:** \(x - y = 1\) and \(y - z = 0\):
     - This leads to \(z^2 - y^2 = 2\), which has no integer solutions.
   - **Case 2:** \(x - y = 0\) and \(y - z = 1\):
     - This leads to \(x^2 - y^2 = 2\), which has no integer solutions.
   - Therefore, no solutions for \(x - z = \pm 1\).

4. **Subcase \(x - z = 2\):**
   - **Case 1:** \(x - y = 2\) and \(y - z = 0\):
     - This leads to \(2z^2 - 2y^2 = 2\) or \(z^2 - y^2 = 1\), which is a contradiction to \(y - z = 0\).
   - **Case 2:** \(x - y = 0\) and \(y - z = 2\):
     - This leads to a similar contradiction as Case 1.
   - **Case 3:** \(x - y = 1\) and \(y - z = 1\):
     - We get \(x^2 - 2y^2 + z^2 = 2\).
     - Here, \(x, y, z\) are consecutive integers, so plug it into the above equation:
       \[ (y + 1)^2 - 2y^2 + (y - 1)^2 = 2. \]
       \[ (y^2 + 2y + 1) - 2y^2 + (y^2 - 2y + 1) = 2. \]
       \[ y^2 + 2y + 1 - 2y^2 + y^2 - 2y + 1 = 2. \]
       \[ 2 = 2. \]
     - This is always true. So \((x, y, z) = (k + 1, k, k - 1)\) works for integer \(k\).

5. **Case \(z \geq y \geq x\):**
   - Consider \(z - x = 1\) or \(z - x = 2\).

6. **Subcase \(z - x = 2\):**
   - **Case 1:** \(z - y = 1\) and \(y - x = 1\):
     - We get \(-x^2 + 2y^2 - z^2 = 2\).
     - Here, \(z, y, x\) are consecutive integers, so plug it into the above equation:
       \[ -(y - 1)^2 + 2y^2 - (y + 1)^2 = 2. \]
       \[ -(y^2 - 2y + 1) + 2y^2 - (y^2 + 2y + 1) = 2. \]
       \[ -y^2 + 2y - 1 + 2y^2 - y^2 - 2y - 1 = 2. \]
       \[ -2 = 2. \]
     - This is a contradiction, so no solutions.

Conclusion:
The only solutions are of the form \((x, y, z) = (k + 1, k, k - 1)\) for integer \(k\).

The final answer is \( \boxed{ (x, y, z) = (k + 1, k, k - 1) } \) for integer \(k\).
