# Industrial Specification: Trigger Mechanism

## 1. Technical Definition
A manual control device that activates and regulates fluid flow in spray guns by user finger pressure.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.3-0.8 MPa (3-8 bar) actuation pressure range**. Failure boundary: **1.2 MPa (12 bar) maximum pressure threshold before seal extrusion**, Mechanism: **Elastomer seal extrusion failure due to exceeding 1.2 MPa differential pressure, causing material flow through clearance gaps exceeding 0.05 mm**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 25 μm in fluid stream | 8 | Seal abrasion and leakage at 0.5 MPa | Install 10 μm absolute filtration upstream with differential pressure monitoring |
| Cyclic fatigue from 10^6 actuations at 0.6 MPa | 8 | Spring fracture at stress concentration points exceeding 800 MPa | Shot peen spring surfaces to induce 200 MPa compressive residual stress |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in this trigger mechanism for durability?
**A**: This trigger mechanism is constructed from zinc alloy for the main body, stainless steel for corrosion-resistant components like the pivot pin, and engineering plastic for wear-resistant parts, ensuring long-lasting performance in industrial environments.

### Q: How does the trigger mechanism regulate fluid flow in spray guns?
**A**: The mechanism uses finger pressure on the trigger lever to actuate a rod or linkage system, which precisely controls the opening and closing of the fluid valve. A return spring ensures smooth resetting for consistent flow regulation.

### Q: What are the main components in the trigger mechanism's bill of materials?
**A**: The BOM includes the trigger lever for user input, a pivot pin for smooth rotation, a return spring for resetting, and an actuation rod or linkage to transfer motion to the fluid control valve.

## 6. Manufacturing Compliance
