Abstract
An electronic angle adjustment mechanism for a pump and a motor generally includes a base and an actuating motor. The base has an upper portion mounted to a motor, a lower portion mounted to a pump, and a hinge for pivotably moving the upper base portion in relation to the lower base portion. The actuating motor is mounted on an attachment plate that is attached to the upper base portion. The actuating motor is connected to a gear wheel that engages an arcuate member attached to the lower portion to pivot about the hinge and change the angle between the upper and lower base portions.
Claims6
An angle adjustment mechanism for a pump and a motor comprising:
- a base including an upper base portion having a first end for mounting a motor and a second end, a lower base portion for mounting a pump on a first end and a second end, and a hinge pivotably connecting said second end of said upper base portion and said second end of said lower base portion;
- an actuating motor having a shaft with a distal end connected to a gear wheel;
- an arcuate member having a plurality of teeth that engage the gear wheel;
- an attachment plate that attaches the actuating motor to the first end of the upper base portion, wherein said attachment plate extends outwardly from the actuating motor and has a sidewall that extends downwardly towards the pump for mounting the actuating motor;
- and
- wherein actuation of said actuating motor drives said arcuate member in a curved path causing said lower base portion and upper base portion to pivot with respect to each other about said hinge, thereby changing an angle between said lower base portion and said upper base portion.
