<p>PURPOSE:To promote the miniaturization, simplification, easiness of manufacture and the cost down of each constitutional member, by holding a seal member by a seal case, inserted into a pump housing, while blocking an opening part of the pump housing by a blind plug. CONSTITUTION:A pump housing 25 is constituted of the first manifold 26 connected to a crankcase 12 inserting a plunger 20 into the inside and the second manifold 28 connected to the first manifold 26 by a bolt 30. And the pump housing 25 forms an insertion hole 42 crossing over each manifold 26, 28 further inserts a seal case 46 into the insertion hole 42. While low and high pressure side seal members 52, 54 are respectively fitted to both sides of the seal case 46. On the other hand, the second manifold 28 removably fixes a blind plug 60 blocking an opening part 44 of the insertion hole 42. Further a coil spring 64 is contractively provided between the blind plug 60 and the high pressure side seal member 54 pressing the high pressure side seal member 54.</p> |
