Title:
エアモータの調速機、及びエアツール
Document Type and Number:
Japanese Patent JP6959641
Kind Code:
B2
Abstract:
A speed governor (20) for an air motor (10) adjusts the rotational speed of the air motor. The speed governor (20) is provided with a governor rod (21), a governor valve (22), a biasing means (23), pressing means (24, 25), and adjusting means (26, 27). The governor valve is provided in such a manner as to be movable along the axis of the governor rod, and increases or decreases the flow rate of a compressed gas to be supplied to the air motor. The biasing means abuts the governor valve at one axial end part thereof, and biases the governor valve in the valve opening direction in which the supply flow rate increases. The pressing means generate a drag force which increases as the rotational speed of the air motor increases, and press, against the biasing force of the biasing means biasing the governor valve, the governor valve in the valve closing direction in which the supply flow rate decreases. The adjusting means adjust the biasing force. As a result, the maximum speed of the air motor can be easily reset.
