Centerlines of the delivery channel, the output channel, and the auxiliary channel are arranged in the same plane.

A pressure reducing valve device includes a first body; a second body; a valve mechanism accommodated in the first body, and including a valve seat and a valve element; and a piston that is accommodated in the second body, defines a pressure reducing chamber, and is configured to move in accordance with a pressure in the pressure reducing chamber so as to move the valve element. The first body is connected to an inner portion of a connection portion having a bottomed cylindrical shape. The connection portion is provided in the second body to protrude outward. The valve seat is held between the first body and the second body in a direction in which the first body and the second body are attached to each other such that the valve seat is fixed in a flow passage.

Pressure reducing valve device

In a pressure reduction valve device, a valve body and a distal end portion of a support member are accommodated in a valve accommodation hole of a body. The distal end portion is inserted through an urging member accommodation hole. An inner introduction passage is formed between an outer peripheral surface of the distal end portion and an inner peripheral surface of the urging member accommodation hole. An outer introduction passage is formed between an outer surface of the valve body and an inner surface of the valve accommodation hole. The support member is provided with communication holes that establish communication between a gas inlet provided through the body and the valve accommodation hole in an axial direction. The inner introduction passage and the outer introduction passage are opposed, in an axial direction thereof, to the communication passage.

Pressure reduction valve device

A pressure reducing valve includes a body, an annular valve seat, a valve element, and a pressing mechanism configured to press the valve element. The pressing mechanism includes a plug provided downstream of the valve seat and having a plug hole, and a pin including a sliding portion and an upstream end, the sliding portion having a shaft shape and being inserted in the plug hole such that a gap is provided between the sliding portion and an inner peripheral surface of the plug hole, and the upstream end being provided upstream of the sliding portion so as to contact the valve element. A fitting length of the sliding portion with respect to the plug hole and the gap between the sliding portion and the plug hole satisfy 0.0005 L&#x3c;C&#x3c;0.00908 L, where L indicates the fitting length, and C indicates the gap.

A valve device includes: a body including a gas passage through which gas flows and an accommodation recess that communicates with the gas passage; a valve mechanism that controls flow of the gas flowing through the gas passage; and a cover fixed to the body such that the cover covers the accommodation recess. In the valve device, the cover includes a cover recess that opens toward the accommodation recess, and the valve mechanism is assembled to the body such that the valve mechanism is accommodated in the accommodation recess with a portion of the valve mechanism protruding from the accommodation recess and the portion of the valve mechanism is accommodated in the cover recess.

Valve device

A throttle valve includes a throttle valve element; a support member that supports the throttle valve element, the support member including a valve element support portion, and a shaft portion that is connected to the valve element support portion, the shaft portion having a gas passage and an inlet port; a mounting member that mounts the support member in a throttle valve flow passage; a filter that is disposed on an outer peripheral surface of the shaft portion to cover the inlet port, in a space whose axial length is defined by the shaft portion and the mounting member; and gaskets that are respectively disposed between one axial end of the filter and the mounting member and between the other axial end of the filter and the shaft portion.

Throttle valve

A hermetic compressor includes a closed vessel for storing lubricating oil, an electric-driving element, and a compressing element driven by the electric-driving element. The compressing element includes a cylinder block forming a compression chamber, a piton that reciprocates inside the compression chamber, and an oiling device for supplying the lubricating oil to an outer circumference of the piston. A first oil groove is concavely formed on the outer circumference of the piston, and a second oil groove is concavely formed on a side opposite to the compression chamber relative to the first oil groove. The second oil groove has a spatial volume same or greater than that of the first oil groove. An expanded clearance portion is provided such that a clearance between the piston and the cylindrical hole portion broadens from a top dead point to a bottom dead point.

Hermetic compressor

A valve apparatus includes a body with a supply passage for gas and a solenoid valve housed in the body.
