Document Type and Number:
Japanese Patent JP2016217333
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric pump capable of reducing the number of components.SOLUTION: An electric pump includes: a motor unit rotatably driving; a speed reduction unit 32 as a transmission unit configured to transmit rotation driving of the motor unit; a pump unit configured to supply fluid with rotation driving force transmitted by the speed reduction unit 32; and a rotary valve that has a plurality of outside fitting holes 86 as a fluid discharge port for discharging fluid supplied from the pump unit to outside, and in which the outside fitting holes 86 are switched with rotation due to rotation driving force transmitted from the speed reduction unit 32. The speed reduction unit 32 has a worm gear 52 that makes a rotational frequency in rotation operation at the time of switching of the outside fitting holes 86 of the rotary valve smaller than the rotational frequency of the motor unit.SELECTED DRAWING: Figure 5
