Abstract

PURPOSE:To obtain the hand pump capable of being used for a refrigerating system of small size and light weight by a method wherein the opening and closing of a suction port and an exhaust port for a cylinder are controlled by a cam device in conjuction with the movement of a hand lever reciprocating a piston. CONSTITUTION:When the lever 15 is swung into left-and-right directions, the movement thereof is converted into a linear motion through a pinion 17 and a rack 16 and the pistons 14a, 14b reciprocate linearly to effect a pumping effect. At this time, the position of a valve 26 is controlled by a cam surface 34 and the opening and closing of the suction and exhaust ports of the cylinder chambers 13a, 13b are controlled. Simultaneously, the movement of the lever 15 is transmitted to an intermittent rotary plate and the positional signal of the lever is produced by a point for signal while the positional signal is utilized for the control signal of an intermittent valve.
