The motor and pump shafts are offset for the most efficient use of force. The main drive housing has a motor mounted at the rear. The gear assembly is formed with a 5 ° helix angle and
Use teeth with a pressure angle of °. This geometry combines the high efficiency of linear cutting gears with the noise reduction characteristic of spiral designs.

The yoke moves up and down relative to the guide rod held in the pocket of the drive housing. Like the gear assembly, the yoke is molded from plastic, so it is inexpensive and easy to manufacture.

はるかに軽量にすることが可能である。A cap having a bearing is provided on the upper end of the pump rod. The pump assembly is designed as a single acting pump. That is, the pump only pumps during the downward stroke and is loaded during the downward stroke. Since the yoke eventually becomes a guide rather than a force applicator, it is possible to make the drive train components, including the yoke and gear, much lighter.

の製造を可能にする。The motor and pinion are offset from the centerline of the pump assembly. Since the pump rod, the pinion, the yoke, the eccentric portion, and the cap are all arranged on the same plane, such a structure does not have an extreme cantilever structure. The position of the rod and single acting pump relative to the gear centerline reduces the thrust load on the yoke. The position of the pinion in the gear is partially offset, reducing the pump force on the gear shaft and bearing. By placing the eccentric bearing directly at the end of the press-fitted pump rod cap, the pump force is not transmitted through the intermediate member such as the yoke, so that the life is extended and the efficiency is improved, and the yoke assembly is cheaper. Enable the manufacture of.

る。The entrance check comprises a check ball and a check sheet that is press-fitted into the check housing and held in place by a retainer. All these parts are press fit together so that replacement requires only screwing the completed assembly into the main pump housing. Similarly, the outlet check assembly, which is formed from an outlet check housing that is screwed into the pump housing, also comprises a check ball that is held in place by a retainer. The outlet passage forms an angle with the axis of the pump shaft. This causes the exit check assembly to operate essentially by gravity, requiring only one passage to be drilled while maintaining essentially a vertical ball-seat relationship.

A gear assembly 16 having a rear bearing 17 and gear teeth 22 is inserted in a bearing housing 20 of the drive housing 12. The gear teeth 22 of the gear assembly 16 engage the teeth of the pinion 24 at the end of the motor 14. The teeth 22 and the teeth of the pinion 24 are formed with a helix angle of 5 ° and a pressure angle of 25 °. This geometry combines the high efficiency of linear cutting gears with the noise reduction characteristic of spiral designs.

なる。An eccentric part 25 is also formed in the front part of the gear assembly 16, and a bearing housing 28 supported in a yoke 30 is arranged around the eccentric part 25. The yoke 30 moves vertically with respect to the guide rod 32 held in the pocket 34 of the drive housing 12. The yoke 30 is molded from plastic. Gear assembly 16 is cast from ZA-12 with an integral counterweight, which is low cost and simple to manufacture.

列の部品をはるかに軽量にすることが可能である。The pump rod 36 includes a cap 38 having a bearing 28 thereon at the upper end. The pump assembly 40 is designed as a single-acting pump, a pump that only pumps on the downward stroke and is loaded on the upward stroke. At that time, since the yoke 30 finally becomes a guide device rather than a force application device, the components of the drive train including the yoke and the gear can be made much lighter.

Further, since the pump rod, the pinion, the yoke, the eccentric portion and the cap are all arranged on the same plane, this structure does not have an extreme cantilever structure. The position of the rod and single acting pump relative to the gear centerline reduces the thrust load on the yoke. The position of the gear pinions is partially offset, reducing pumping force on the gear shaft and bearings. By arranging the eccentric bearing directly on the end portion of the press-fitted pump rod cap, the pump force is not transmitted through the intermediate member such as the yoke, so that the life is extended and the efficiency is improved.
Enables the manufacture of cheaper yoke assemblies.

All of these parts are press fit together so that replacement requires only screwing the complete assembly into the main pump housing 48. Similarly, an outlet check assembly formed from an outlet check housing 60 screwed into the pump housing 48 is
A check ball 62 held in place by a ball seat 65 is also provided. As also seen in FIG. 7, the outlet passage 66 is angled with respect to the axis of the pump shaft 36. This allows the exit check assembly 58 to operate essentially by gravity, requiring only a single passage to be drilled while maintaining essentially a vertical ball-seat relationship.
