## Abstract

A fluid control valve includes a housing body, a valve member, and a cap. The housing body includes a pipe part and a valve housing part. The valve housing part includes a valve opening, a pair of flat surfaces and an open end. In addition, the valve housing part houses the valve member configured to open and close the valve opening. The valve housing part has a central axis oriented perpendicular to a central axis of the pipe part. The cap closes the open end of the valve housing part. The flat surfaces are formed on opposite sides of a plane including the central axis of the valve housing part and the central axis of the pipe part. Each of the flat surfaces extend perpendicularly to the central axis of the valve housing.

## Claims

### Claim 1

A fluid control valve, comprising:
a housing body including
a pipe part having a flow passage therein; and
a valve housing part including a valve chamber, a valve opening, a pair of flat surfaces and an open end, wherein the valve housing part has a central axis oriented perpendicular to a central axis of the pipe part, the valve opening fluidly communicating the valve chamber with the flow passage, wherein the flat surfaces are disposed on opposite sides of a plane including the central axis of the valve housing part and the central axis of the pipe part, wherein each of the flat surfaces extends perpendicularly to the central axis of the valve housing part;
a valve member housed in the valve chamber and configured to open and close the valve opening;
a cap closing the open end of the valve housing part; and
a spring disposed between the valve member and the cap, wherein the spring biases the valve member toward the valve opening.

### Claim 2 (depends on 1)

The fluid control valve according to claim 1, further comprising:
a secondary molded member made from a resin material and coupling the cap with the housing body in a non-removable manner.

### Claim 3 (depends on 2)

The fluid control valve according to claim 2, wherein the secondary molded member has a ring shape and extends about an entire periphery of the cap and the valve housing part.

### Claim 4 (depends on 1)

The fluid control valve according to claim 1, wherein the housing body includes an engaged part; and
wherein the engaged part is configured to engage with an engaging part of a workbench to prevent the fluid control valve from moving in the axial direction of the pipe part while the fluid control valve is mounted on the workbench.

### Claim 5 (depends on 4)

The fluid control valve according to claim 4, wherein the engaged part has a convex shape protruding from the pipe part of the housing body.

### Claim 6 (depends on 4)

The fluid control valve according to claim 4, wherein the engaged part has a concave shape recessed from a bottom surface of the pipe part.

### Claim 7 (depends on 4)

The fluid control valve according to claim 4, wherein the engaged part is positioned on the central axis of the valve housing part.

### Claim 8 (depends on 1)

The fluid control valve according to claim 1, wherein the open end of the valve housing part is oriented parallel to the central axis of the valve housing part.

### Claim 9 (depends on 1)

The fluid control valve according to claim 1, wherein the valve housing part is concentric with the cap.

### Claim 10 (depends on 1)

The fluid control valve according to claim 1, wherein both of the flat surfaces extend along a plane oriented perpendicular to the central axis of the valve housing part.
