Class Information
Number: 188/302
Name: Brakes > Internal-resistance motion retarder > Having a thrust member with a variable volume chamber (e.g., coaxial or telescoping tubes, compensating reservoir) > Rectilinear reciprocation of piston caused by arcuately oscillating frame, shaft, arm, axle, etc.
Description: Device wherein a mechanism is connected to the device by an arm pivoted thereto so that movement of the mechanism causes movement of the arm to-and-fro in an arc of a circle, and wherein said arm is connected to a thrust member so as to cause movement of said thrust member to-and-fro in a straight line within a chamber.
