Title: Unitary elevator up level control valve
IPC: B66B1/04
Filed: 1977-01-05
Abstract: 1526681 Valves ELEVATOR EQUIPMENT CO 5 Jan 1977 [12 March 1976] 00200/77 Heading F2V A valve comprises a housing 10 having a chamber 11 for connection to a hydraulic ram 25 of an elevator and a chamber 13 connected to a source 17 of fluid pressure, separated by a partition 14 having a through-passage 35 which check valve member 37 is normally biased to close, a further chamber 12 separated from the chamber 13 by a partition 15 having a throughpassage 42 which can be closed by a valve member 44, a passage 67, which a valve member 69 is biased to close, for applying pressure from a pilot pressure line 20 connected to the source 17 to the valve member 44, a stem 55, 58 connected to the check valve member 37 and extending through the valve member 44 to engage the valve member 69, and a line 75 controlled by a solenoid valve 76 for supplying fluid from the line 20 to the valve member 44 independently of the passage 67. There is a further solenoid valve 61 and a variable restrictor 62 in the line 20, and a further variable restrictor 79 in a line 78 connecting the line 75 to the chamber 12, which is connected to tank 16. When the elevator is to be raised the pump 17 is started (circulating fluid back to tank 16 via chamber 13, passage 42 and chamber 12) and valves 61, 76 are opened, supplying fluid via passages 67 and line 75 to raise valve member 44 to close the passage 42, so that the pressure in chamber 13 rises and raises the check valve member 37 to supply the ram 25; this raises the stem 55, 58, allowing the valve member 69 to seat, so that the valve member 44 is supplied with fluid solely through the line 75 at a pressure determined by the setting of the variable restrictors 62, 79. At a point in the travel of the ram 25 the solenoid valve 76 is de-energized, so that the fluid beneath the valve member 44 is vented via the restrictor 79, the valve member 44 partially opening the passage 42, allowing the pressure in the chamber 13 to fall so that the check valve member 37 moves towards its seat, reducing the flow to the ram 25 and at the same time causing the stem 55, 58 to unseat the valve member 69, so that an equilibrium position of the check valve member 37 is established in which the ram 25 moves at a reduced speed. At a further point in the travel of the ram the valve 61 is de-energized and the ram stopped.
