Control apparatus for a water powered sump pump

A water powered sump pump having a specific installed orientation in a sump, the sump pump comprising:

• a drain line locatable in the sump in which water may collect;
• an inlet port connectable to a source of water under pressure;
• a fluid outlet port in fluid communication with the drain line to draw a flow of water into the drain line from the in response to a flow of water from the fluid outlet port;
• and
• a flow control apparatus in communication with the inlet port and the outlet port to control flow from the inlet port to the outlet port, the flow control apparatus comprises:
• a passage connecting the inlet port to the outlet port,
• a flow valve moveable from a closed position in which the passage is closed to an open position in which the passage is open, the flow valve biased to the closed position,
• a variable pressure chamber separated from said passage by said valve,
• a low volume water passage in fluid communication with the inlet port and the variable pressure chamber, and
• a control valve in fluid communication with the variable pressure chamber, the control valve moveable in a valve chamber between an open position of the control valve wherein a water flow is allowed to exit the variable pressure chamber via the control valve thereby initiating movement of the flow valve from the closed position of the flow valve to the open position of the flow valve, and a closed position of the control valve wherein water cannot exit the variable pressure chamber via the control valve thereby initiating movement of the flow valve from the open position of the flow valve to the closed position of the flow valve;
• and
• an actuator assembly comprising:
• a pivotally supported actuator lever engaged with the control valve to actuate the control valve between the closed and open positions, the actuator lever mounted to pivot between a first position wherein the control valve moves to the closed position of the control valve in response to engagement with the actuator lever, and a second position wherein the control valve moves to the open position of the control valve in response to engagement with the actuator lever, the actuator lever extending longitudinally from a first portion of the actuator lever engaged against the control valve to a second portion of the actuator lever having an aperture configured for direct engagement with a float assembly to transmit force to actuate the lever between the first and second positions;
• and
• a biasing member pivotably attached to the actuator lever and mounted for movement between a first bias position wherein the biasing member biases the actuator lever to the first position with the actuator lever in the first position and a second bias position wherein the biasing member biases the actuator lever to the second position with the actuator lever in the second position.
