Abstract
221,836. Nichols, T. W. March 21, 1923. Combined fluid-actuated and mechanical gears ; expansion valves. -An expansion valve or an auxiliary distributing-valve acting as an expansion valve, is housed in a chest formed integral with the main cylinder and loca.ted between the latter and the distributing valve-chest which constitutes a removable expansion-valve chest cover. In the gear shown, which is similar in operation to the gear described in Specification 208,734, the expansion valve b works in an exhaust chamber, is provided with a balance piston f through which pressure fluid is supplied to auxiliary distributing-ports i, i<1>, and has a main port b<4> which alternately puts the central port a<5>, connected to a main supply passage q cast in the cylinder, in communication with ports a<4>, which by means of the main valve are alternately put into communication with ports q<1>, q<2> leading to the cylinder ends. The cylinder exhaust passes through ports q<1>, q<2> respectively and port q<3>, the chest m, and a passage r<1> cast in the main cylinder. The gear may be modified to function similarly to the gear described. in Specification 3023/15.
