A trigger assembly and mechanically-actuated pneumatic valve provide improved feel and performance for a pneumatic gun. The trigger assembly can include a trigger having a cam-shaped contact surface. A separate actuator can be arranged between the trigger and a valve actuator. The contact surface of the trigger contacts the actuator to cause a contact surface of the actuator to actuate the valve actuator. Roller bearing contact surfaces can be provided on one or both ends of the actuator to reduce friction between the contact surfaces. The valve actuator may control a face seal, pin valve, and plug member to control distribution of gas within the valve. The face seal and pin valve members can redundantly seal an exhaust port. The plug member can seal off an input port during a firing operation of the pneumatic gun to improve gas efficiency.

A compressed gas gun including a housing and a bolt movable within a passage in the housing. Movement of the bolt relative to the housing opens a flow path for firing a projectile.

The valve device includes a main member for installing on a toy gun and connecting to a high-pressure gas source. Inside the main member, there is a first chamber, a second chamber connected to the first chamber, and an inlet channel. A valve member is movably housed in the main member. The valve member includes a valve channel, a through hole, an inlet blocking element, and an outlet blocking element. The valve member selectively blocks the connection between the first chamber and the inlet channel. As such, the pressure difference between the second chamber and the high-pressure gas source drives the valve member to selectively block the inlet channel, without using a spring to control the valve member. The valve device therefore has enhanced operation life and reduced cost.

A dart launcher having few but integral parts and an assembly process that is quick and easy for forming robust but inexpensive toys. The launcher may have an outer body, a safety valve and spring, a valve cap, a trigger, a piston, a launch spring, a cylinder cap and a plunger rod. The outer body includes an integral cylinder portion, a barrel portion and a trigger-mounting portion, the trigger includes an integral finger pad portion, a latch arm, a biasing portion and resilient legs. The piston includes an opening and a connector component formed around the opening to snap-fit with the piston, the cylinder cap includes an opening for the plunger rod and a connector component to connect with the cylinder portion, and the barrel portion includes a valve and mandrel support for supporting the safety valve and spring.

A differential pressure type inflating device, adapted for fast inflating the devices that need inflating, comprises a gas container, a relief valve, a gas nozzle, a pipe joint, a switch valve, and a relief pipe. When external high pressure gas enters the gas container and renders the gas pressures in the gas container and the relief pipe reaching a balance condition, the switch valve can be pressed to generate pressure drop in the relief pipe, which launches the relief valve and discharges the high pressure gas in the gas container from the gas nozzle. In this design, the gas container, relief valve, gas nozzle, relief pipe, and pipe joint are connected with screwing structures, so as to achieve the function of easy assembling.
