횡형 내접 기어 펌프(1)는, 복수의 내치를 가지는 아우터 로터(2) 내에, 복수의 외치를 가지는 이너 로터(3)가, 외치가 내치에 맞물리고, 또한, 편심된 상태로 회전 가능하게 수용되고, 내치와 외치의 사이에, 액체를 흡입하는 흡입측 용적실과, 이 흡입측 용적실에 흡입한 액체를 토출하는 토출측 용적실이 형성되는 트로코이드(4)와, 트로코이드 회전면에 대해서 비수직 방향으로 연장 설치되어서 선단을 액체 저장소(18)에 침지시킨 액체 흡입 노즐(9)과, 트로코이드를 수용하는 오목부(5a)가 형성된 펌프 케이싱(5)과, 상기 오목부를 폐색하는 펌프 커버(6)를 가지고, 펌프 케이싱(5)에 액체 흡입 노즐(9)을 가지는 흡입 커버(8)가 고정되고, 액체 흡입 노즐(9)과 흡입 커버(8)가 수지 조성물의 사출 성형에 의해 일체로 성형되어 있다. Provided is a transverse internal gear pump that can be manufactured at low cost, and also has a high safety factor in terms of functionality. This transverse internal gear pump 1 has a trochoid 4, in which an inner rotor 3 having a plurality of outer teeth is rotatably accommodated within an outer rotor 2 having a plurality of inner teeth, the inner rotor being rotatably accommodated within the outer rotor in an eccentric state and with the outer teeth and the inner teeth meshing, and in which an intake-side volume chamber for taking in a liquid and an ejection-side volume chamber for ejecting liquid taken into the intake-side volume chamber are formed between the inner teeth and the outer teeth; a liquid intake nozzle 9 extending in a non-perpendicular direction with respect to the trochoid rotation surfaces and having a distal end immersed in a liquid reservoir 18; a pump casing 5 in which a recessed portion 5a for accommodating the trochoid is formed; and a pump cover 6 for closing off the recessed portion. An intake cover 8 that has the liquid intake nozzle 9 is secured to the pump casing 5, and the liquid intake nozzle 9 and the intake cover 8 are integrally molded by the injection molding of a resin composition.
