Abstract (en)
The present invention provides a cooling structure of a cylinder block, the cooling structure being capable of improving a cooling performance of sliding surfaces. A cylinder block 12 includes a plurality of cylinders 20, and pistons 13 are respectively inserted into the cylinders 20 through openings. Each of the pistons 13 performs reciprocating sliding on a sliding surface 12b which defines the cylinder 20. A plurality of cooling depressions 31 are formed on an outer peripheral surface 12a of the cylinder block 12. Each of the cooling depressions 31 extends from a front end surface of the cylinder block 12 on a dividing wall 32 located between the two adjacent cylinders 20 and is formed by reducing the thickness of the dividing wall 32 so as to reduce a thickness t of a portion between the sliding surface 12b and the outer peripheral surface 12a.
