<p>PROBLEM TO BE SOLVED: To provide a highly efficient gear pump capable of improving sealability of a connection between a side plate and a seal block, without reference to materials for the side plate and the seal block.SOLUTION: A seal block 6 is formed in a step shape having an inner wall surface 61c for forming a fluid chamber between itself and a tooth space of a gear 4, and a connection JL is provided between the inner wall surface 61c and an outer peripheral surface 7a of a side wall 7. In a high-pressure region HPR on the outside of an annular seal member 81, at least the inner wall surface 61c comprises a connection sealing member 82 that seals the connection JL of a part for forming the fluid chamber.</p> |
