Definitions

  • the invention relates to a control for a boat drive with a motor and an adjustable propeller, the pitch of which is adjustable with the aid of a hydraulic actuator, wherein the working spaces of the actuator are assigned valves which can be actuated by an actuator.
  • the actuator is an adjusting lever on the driver's cab of the boat, which actuates the hydraulic actuator or its valves. Since boat drives with a motor and variable-pitch propeller are sensitive systems, the damage-free operation of which requires experience from the boat operator, a regulation has also been proposed according to a proposal that is not yet state of the art (DE 39 01 137). However, such a control is structurally and technically complex and therefore expensive. Repairs and maintenance can only be carried out in qualified workshops.
  • the object of the invention is to provide a constructionally and circuit-technically simple and easy-to-use control for a boat drive with variable pitch propeller, which is also safe against incorrect operation.
  • valves are designed as solenoid valves, each of which is preceded by a time relay which can be actuated by the actuator, and in that the motor has a tachometer which when a certain engine speed is exceeded, the time relay of the solenoid valve responsible for increasing the wing pitch is actuated.
  • the tachometer should actuate the timing relay when the maximum engine speed is exceeded.
  • the engine since every time the wing pitch changes, the engine reacts by increasing or decreasing its speed and over-revving the engine can cause serious damage, the engine has a tachometer that, when the maximum engine speed is exceeded, the timing relay for increasing the wing pitch responsible solenoid valve actuated. Even if the operator tries to reduce the pitch of the variable-pitch propeller in the area of the maximum engine speed, the wing pitch is increased again when the maximum speed is reached, so that the engine speed drops, for example, by an amount of 300 rpm.
  • the motor 1 is an internal combustion engine which drives the variable propeller 2 via a shaft 3.
  • the adjusting propeller 2 has a hydraulic actuator integrated therein, which adjusts the propeller blades 4 via an adjusting mechanism (not shown).
  • Each working area of the hydraulic actuator is assigned a solenoid valve 5 or 6, which controls the inflow to the respective working area.
  • the solenoid valves 5, 6 are in turn controlled by time relays 7, 8, which are triggered by electrical pulses from a rocker switch 9.
  • the solenoid valve 5 opens for a certain time, e.g. 50 - 200 mm / sec, and the pitch of the propeller blades 4 is reduced by 1/2 to 1 °.
  • the solenoid valve 6 opens and the pitch of the propeller blades 4 is increased by a corresponding amount.
  • a tachometer 10 which detects the engine speed is provided, which emits a signal to the timing relay 8 when the maximum speed of the engine 1 is exceeded, so that this is triggered and activates the associated solenoid valve 6, thus increasing the pitch of the propeller blades 4 is enlarged. As a result, the engine speed drops by a corresponding amount.
