摘要： A movable valve element (24) is comprised of a valve member (22) and a leaf spring (26). A passage forming member (12) is securely fixed to a valve chamber forming member (10) that forms a valve chamber (S). The passage forming member (12) has a fluid passage (14) extending from one end to the other end thereof, with the one end (14a) of the fluid passage (14) constituting an outlet port of the valve chamber (S). The passage forming member (12) has an O-ring (20) surrounding and spaced apart from the outlet port (14a), the O-ring (20) constituting a valve seat. Spring force of the leaf spring (26) brings the valve member (22) into pressure contact with the O-ring (20), to form a closed valve state.

摘要： According to an embodiment of the present invention, a hand-held electric working machine for cutting a work object is provided. The electric working machine comprises a working portion, a housing, a motor, and a control unit. The working portion is configured to cut the work object. The housing extends in a first direction from a rear side where a user is positioned to a front side where the work object is positioned. The motor is configured to generate rotary power for allowing the working portion to drive and is provided on the rear side of the housing, displaced in a second direction with respect to a centerline of the housing. The centerline extends in the first direction, and the second direction is perpendicular to the first direction. The control unit is configured to electrically control rotation of the motor and is positioned opposite the motor across the centerline.

摘要： Provided is a vacuum blower, when used as a vacuum for sucking work, capable of increasing air flow with a larger volume of air sucked from a suction port and increasing the initial velocity (sucking rate) of sucked objects near the suction port, and when used as a blower for blowing work, capable of delivering rectilinearly directed wind from the blowing port and quickly switching between sucking work and blowing work. By sliding an inner pipe 14 disposed inside a pipe 10 relative to the pipe 10, opposite end portions of the inner pipe 14 come into close contact with opposite end portions (turn portions 15, 16) of a nozzle 40 facing the opposite end portions of the inner pipe 14, such that one ejection port (42, 43) is closed and the other ejection port (43, 42) is opened to allow pressurized wind generated by a blower fan 20 to be ejected along the inside of the inner pipe 14 to switch between sucking state and blowing state.

摘要： Provided is power work equipment using a fuel container and/or a lubricating oil container that is/are easily replaced for the power work equipment, and supply(ies) liquid fuel and/or lubricating oil optimized for driving. A chainsaw (1A) (power work equipment) includes a main body (10) having an internal combustion engine (50), and a fuel container (90A) and/or a lubricating oil container (100A) detachably attached to the main body (10). A connection part (92) of the fuel container (90A) is connected with the fuel suction unit (60) in a liquid-tight manner, and a bag (91) is configured to collapse as liquid fuel (F) in the bag (91) decreases. A connection part (102) of the lubricating oil container (100A) is connected with a lubricating-oil suction unit (70) in a liquid-tight manner, and a bag (101) is configured to collapse as lubricating oil (L) in the bag (101) decreases.

摘要： A lawn mower capable of securing desired durability as well as suppressing a weight increase is provided. When prong portions 41 on the periphery of a bottom disk 40 are elastically deformed inward due to an external force applied thereto, the prong portions 41 abut a cutting disk 35, so that the received external force is transferred to the cutting disk 35 (that is, the external force is partially received by the cutting disk 35), and the displacement of the prong portions 41 is restricted by the presence of the cutting disk 35.

摘要： To improve responsiveness of fuel supply control, a rotary carburetor 100 has a nozzle 8 including a fuel discharge port 8a and a needle 10 disposed coaxially with the nozzle 8 and disposed with a portion inserted into the nozzle 8. The needle 10 can be displaced relative to the nozzle 8 to change an effective area of the fuel discharge port 8a. The rotary carburetor 100 has an electric motor 14 for displacing the needle 10 along an axis, and a drive mechanism component 12 interposed between the electric motor 14 and the needle 10 and converting a rotational movement of the electric motor into a linear movement.

摘要： The efficiency of charging air to a scavenging channel is enhanced by generating a gas flow in a piston groove simultaneously with the piston groove coming into communication with an air port. A piston groove 8 formed in a peripheral surface of a piston includes a pressure transmission through hole 10, and the pressure transmission through hole 10 consistently communicates with a crankcase. In the course of the piston moving up, upon a pressure in the crankcase becoming negative, the negative pressure in the crankcase affects the piston groove 8 through the pressure transmission through hole 10. Consequently, a pressure in the piston groove 8 is released to the crankcase through the pressure transmission through hole 10. Upon the piston moving up and the piston groove 8 being thereby brought into communication with the air port 4a, air enters the piston groove 8 through the air port 4a ((III) of FIG. 1).
