The invention provides a motor-operated valve including a planetary gear mechanism achieving a greater reduction gear ratio without increasing the number of teeth of the gears, thereby enabling downsizing. In a planetary gear mechanism 1, a sun gear 91 functioning as an input gear receives smaller load than an internally toothed output gear 45, so gears (second planet gears 95) having a smaller module are connected to the planet gears 93, and the sun gear 91 is in engagement with the second planet gears 95. The sun gear 91 is formed of a same module as the second planet gears 95. The rotation of the sun gear 91 is reduced in speed and transmitted to the second planet gears 95, and rotation of the second planet gears 95 rotated at a reduced speed is further reduced by the slight difference in the numbers of teeth of the ring gear 44 and the internally toothed output gear 45 before being output.

The female screw part and projection part are integrally molded with a resin. The projection part has a spiral inclination face spirally inclining by one round from the working face centering on the center shaft of the female screw. The height H of the working face is equal to or smaller than a pitch P of the female screw. Using the projection part as a fully opening fixing stopper, a motor operated valve includes a valve main body having a valve seat, the female screw member attached to the valve main body, a motor having a rotator and stator, and a valve shaft. The valve shaft is screwed to a female screw of the female screw member, and is rotated and driven by the rotor, and has a fully opening movable stopper capable of contacting the fully opening fixing stopper.

A passage adapted to selectively place the fluid inlet port or the fluid outlet port in communication with the plurality of fluid in/out ports is formed within the valve member. Flow paths are reversed by rotating the valve member to selectively place the fluid inlet port or the fluid outlet port in communication with one of the plurality of in/out ports via the passage. The rotational axis line of the valve member is laterally eccentric relative to the rotational axis line of an output shaft of the actuator by a predetermined distance.

A drain pump that maintains pump performance and reduces noise and vibration accompanying water scooping of a rotary impeller includes a large-diameter blade divided into an inner blade and an outer blade. A radius of an impeller scooping up water is the sum of the lengths of the inner and outer blades in a radial direction. The large-diameter blade is divided at a position where the amount of generated air bubbles is large, and the inner and outer blades are alternately disposed. Accordingly, air bubbles are escaped to a downstream side in a rotational direction, so that the intensity of the collision between the blades and air bubbles is decreased reducing noise caused by the burst of air bubbles and vibration caused by a collision load of the flow of a gas-liquid mixture.

A motor-operated valve configured to control the flow rate during a normal flow and pass the fluid so as to minimize pressure loss during a reverse flow, and a refrigeration cycle using the same, are provided. It is configured such that during a normal flow, the fluid is made to flow only from between the main valve member and the orifice to perform flow rate control, and during a reverse flow, all or a majority of the fluid is made to flow to a bypass channel without being passed through the orifice to decrease pressure loss as much as possible. A check valve member which closes the bypass channel during a normal flow and opens it during a reverse flow is provided in the valve main body.
f) and the valve opening is altered to control the flow rate of the refrigerant. The valve body (21) consists of a body upper portion (40) and a body lower portion (41) narrower than the body upper portion (40), and bolt fitting grooves (43, 43) opening in the flank of the valve body (21), preferably opening obliquely downward, are formed at the boundary (42) of the body upper portion (40) and the body lower portion (41). With such a layout, the material required at the boundary (42) can be reduced furthermore and the quantity of material required for the valve body (21) can be reduced furthermore, as a result. Since the opening width (minimum spatial dimension) w is smaller than the diameter of bolt, a seating surface is assured sufficiently around the bolt fitting groove (43) and the bolt does not drop off from the bolt fitting groove (43).
