Abstract: A hydraulic pump and double acting air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. A pilot valve operated by the air piston controls one operating valve for the cylinder and a pilot relay valve. The pilot relay valve controls another operating valve which is in reverse phase with respect to the first operating valve. A muffler which inhibits ice formation is operatively associated with the operating valves for muffling the noise of the air being exhausted from the air cylinder through the operating valves with minimal accumulation of ice.

Abstract: A hydraulic pump and double acting air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. A pilot valve operated by the air piston controls one operating valve for the cylinder and a pilot relay valve. The pilot relay valve controls another operating valve which is in reverse phase with respect to the first operating valve. The piston operated pilot valve has a snap action feature so that the pilot valve, the pilot relay valve and the operating valves all reverse condition abruptly with a minimum dwell to provide a smoother power transmission.

Abstract: A modular apparatus for heating circulating liquids such as paint. The apparatus has a heater module that may be heated internally to a high temperature by electrical energy for example, and one or more interchangeable circuit modules having a relatively high thermal conductivity and positioned face to face against the heater module in heat transfer relationship therewith. Each circuit module has a group of generally parallel internal passages formed for example during extrusion and interconnected in pairs at their ends so as to define a sinuous circuit for liquid between inlet and outlet ports. One circuit module may be secured on each opposite face of the heater module with the two respective groups of passages interconnected through the interposed heater module to form a continuous series connection between the two circuit modules. Two or more such units may be ganged with a series circuit connection to enlarge the circuit and increase the volumetric capacity.

Abstract: A hydraulic pump and double-acting air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. A pilot valve operated by the air piston controls one operating valve for the cylinder and a pilot relay valve. The pilot relay valve controls another operating valve which is in reverse phase with respect to the first-operating valve. The piston-operated pilot valve has a snap action feature so that the pilot valve, the pilot relay valve and the operating valves all reverse condition abruptly with a minimum dwell to provide a smoother power transmission. Also a muffler which inhibits ice formation is operatively associated with the operating valves for muffling the noise of the air being exhausted from the air cylinder through the operating valves with minimal accumulation of ice.
Abstract translation: 一种液压泵和双作用气动马达，包括用于控制空气进入和排出气缸中的活塞在气缸中的两侧的装置。 由空气活塞操作的先导阀控制用于气缸的一个操作阀和先导继动阀。 先导继动阀控制另一个与第一操作阀相反的操作阀。 活塞操作的先导阀具有快动特征，使得先导阀，先导继动阀和操作阀全部以最小的停留位置突然倒转，以提供更平滑的动力传递。 还有一种阻止冰层形成的消音器与操作阀可操作地相关联，用于消除通过操作阀从气缸中排出的空气的噪音，并以最小的积冰积聚。
